    • The invention comprises phthalimidomethylanilines of formula: where R represents hydrogen or one or more substituents selected from halogen, nitro, alkyl and alkoxy; R1 is hydrogen or alkyl; R2 is nitro, aliphatic (defined as including cycloaliphatic and araliphatic) hydrocarbyl (provided that where R is hydrogen said group contains two or more carbon atoms); aliphatic-oxy (provided that where R is hydrogen said group contains three or more carbon atoms); a group having the structure: where R is hydrogen or an inert substitutent (e.g. alkyl or alkoxy) and there is also present a substituent R3 in the nucleus to which a group R2 of this structure is attached; or R2 is -NR4R5 where both R4 and R5 are alkyl or R4 is hydroge and R5 is alkyl, aryl or acyl (which may be derived from a carboxylic or sulphonic acid), or (provided the group -NR4R5 is in the o- or m-position to the nitrogen atom to which R1 is linked) a phthalimidomethyl group. They are prepared by reacting a phthalimide, formaldehyde and an aniline either simultaneously, or by adding the aniline to a preformed mixture of formaldehyde and the phthalimide, or by first making an N-hydroxymethylphthalimide from formaldehyde and the phthalimide and reacting this with the aniline. An inert diluent may be used. Temperatures of 0-100 DEG C. are mentioned. The products are vulcanisation accelerators (see Division C3). N-hydroxymethylphthalimide is prepared from phthalimide and formalin.ALSO:Vulcanisation accelerators for natural and synthetic rubbers comprise phthalimidomethylanilines of formula: where R represents hydrogen or one or more substituents selected from halogen, nitro, alkyl and alkoxy; R1 is hydrogen or alkyl; R2 is nitro, aliphatic (defined as including cycloaliphatic and araliphatic) hydrocarbyl (provided that where R is hydrogen said group contains two or more carbon atoms); aliphatic-oxy (provided that where R is hydrogen said group contains three or more carbon atoms); a group having the structure. where R3 is hydrogen or an inert substituent (e.g. alkyl or alkoxy) and there is also present a substituent R3 in the nucleus to which a group R2 of this structure is attached; or R2 is - NR4R5 where both R4 and R5 are alkyl or R4 is hydroge and R5 is alkyl, aryl or acyl (which may be derived from a carboxylic or sulphonic acid), or (provided the group -NR4R5 is in the o- or m-position to the nitrogen atom to which R1 is linked) a phthalimidomethyl group.

    • An (N:N-disubstituted-amino)-methyl-2-alkylphenol is obtained by the reaction of a 2-alkylphenol, wherein the alkyl group is n-tridecyl, n-tetradecyl or n-pentadecyl, with formaldehyde and a secondary amine R1R2NH, wherein R1 and R2 are alkyl groups or together form an alkylene chain which may be interrupted by another hetero atom. In an example 4-bromoanisole is condensed with myristoyl chloride in presence of aluminium chloride to give 4-bromo-2-myristoyl-anisole, this is reduced by means of zinc amalgam and hydrochloric acid to 4-bromo-2-n-tetradecylanisole, this is refluxed with hydriodic acid to give 2-n-tetradecylphenol and this is reacted with dimethylamine and paraformaldehyde to give an N:N-dimethylaminomethyl-2-n-tetradecylphenol, the hydrochloride of which is also described. Other amines referred to are diethylamine, di-n-propylamine, morpholine and piperidine, and other salt-forming reagents mentioned are hydrohalic acids and alkyl halides. The products of the invention are stated to have anti-tubercular properties.

    • The invention comprises a process for the preparation of 2-(N,N - disubstituted - amino)-methyl-4-alkyl phenols of the structure (in which the R's are alkyl groups or together form a chain, the ends of which are linked to the N atom, and R1 is an alkyl group of at least 4 carbon atoms), by reduction of the corresponding alkyl-salicyl-disubstituted amides of the structure The reduction is preferably carried out by means of lithium aluminium hydride in an anhydrous system; but catalytic hydrogenation may also be employed. In an example, a mixture of 5-n-tetradecylsalicyldimethylamide, dry ether and lithium aluminium hydride is refluxed; and then, after standing overnight, the reaction-mixture is treated with aqueous sodium hydroxide and wet ether. Filtration and evaporation of ether from the filtrate gives 2-dimethylamino-methyl-4-n-tetradecylphenol. This compound together with its salts, is claimed per se. The hydrochloride is prepared by dissolving the free base in methanolic hydrogen chloride, and then allowing the solution to evaporate. This salt has anti-tubercular properties. It is stated that the R groups, in the above formul , can form with the N atom a piperidine or morpholine ring. 5 - n - Tetradecylsalicyldimethylamide is obtained by the action of thionyl chloride, followed by dimethylamine, on 5-n-tetradecylsalicylic acid. 5-n-Tetradecylsalicylic acid is obtained by the reduction of 5-myristoylsalicylic acid with zinc amalgam and aqueous hydrochloric acid. 5-Myristoylsalicylic acid is obtained by the reaction between salicylic acid and myristoyl chloride in the presence of aluminium chloride.

    • The invention comprises N,N,N11,N11-tetramethyldithiobiurets in which the central nitrogen atom (N1) is substituted by an aryl group having a chloro, methoxy, ethoxy or nitro substituent, and a process for the preparation of N,N,N11,N11-tetraalkyldithiobiurets in which a dialkylthiocarbamyl chloride is reacted with a primary arylamine in the presence of a tertiary amine. Preferably, substantially one molecular proportion of primary arylamine is used for each two molecular proportions of dialkylthiocarbamyl chloride and at least one molecular proportion of tertiary amine is used for each molecular proportion of the latter. In examples, p-chloroaniline is reacted in toluene with N : N-dimethylthiocarbamyl chloride in the presence of pyridine to yield N : N : N11 : N11-tetramethyl - N1 - (p - chlorophenyl) dithiobiuret, and N : N : N11 : N11 - tetramethyl - N1 - (p-ethoxyphenyl) dithiobiuret is obtained by reacting p-phenetidine with N : N-dimethylthiocarbamyl chloride in the presence of pyridine. Additional starting materials specified are aniline, a -naphthylamine, o-chloroaniline, 2 : 4 - and 3 : 4 - dichloroaniline, o - and p-anisidine, o-phenetidine and p-nitraniline.
