Amines of the formula R.HN.X.Y used as starting materials are made by catalytically hydrogenating corresponding aldehydes or ketones in the presence of ammonia or an amine RNH2, followed if required by hydrogenation of the furan or pyran ring. Alternatively a furan carboxylic amide may be reduced to an amine with lithium aluminium hydride or a cyano-furan, e.g. a -methyl-a -cyanofuran, may be hydrogenated and the resulting amine alkylated, giving, for example, a -methyl-a -tetrahydrofurfuryl-methylamine. 2 - Sulphamoyl - 4 - [N - methyl - N - (cyclopentylmethyl)-sulphamoyl]-chlorobenzene is made by reacting cyclopentylmethylamine with formic acid ester to give N-formyl-cyclopentylmethylamine, reacting with lithium aluminium hydride to give N-methyl-cyclopentylmethylamine and reacting with 4-chloro-3-sulphamoylbenzenesulphonyl chloride.

Novel disulphonamides (and salts thereof) of the general formula (and also the corresponding compounds wherein the heterocyclic ring is broken between the members N and X and accordingly the resulting nitrogen bond is satisfied by a hydrogen atom and X is a carboxy (-COOH) group) wherein R is H or Me, R 1 is H or C 1-4 alkyl, R 11 is H, C 1-4 alkyl, alkoxyalkyl, aryl or aralkyl, X is carbonyl or methylene and n is 0 or 1 are prepared by the interaction of 4-chloro-3-sulphonamido-benzenesulphochloride and the appropriate aminomethyl- or methylamino -compound. Pharmaceutical compositions having diuretic and saluretic activity, and suitable for the treatment of hypertension, contain as the active ingredient the above novel compounds and are preferably administered parenterally in the form of capsules, tablets, pills, powder, granulates or suppositories and ampoules or drops. N - # - Methoxyethyl -, N - benzyl - and N - #- phenethyl - 5 - methyl - 5 - cyano - pyrrolidone- (2) are prepared by the interaction of laevulinic acid ethyl ester cyanohydrin and #-methoxyethylamine, benzylamine or #-phenethylamine respectively. Reduction of the cyano groups therein yields the respective N-substituted-5- methyl - 5 - aminomethyl - pyrrolidone - (2); N- methyl - and N - ethyl - 5 - methyl - 5 - aminomethyl-pyrrolidone-(2) are also described. Treatment of the 5-methyl-5-aminomethyl-pyrrolidones, wherein the N-substituent is a methyl, ethyl, benzyl or #-methoxyethyl group or attached to nitrogen is a hydrogen atom, with benzaldehyde and dimethyl sulphate yields the corresponding 5-methyl-5-methylaminomethylpyrrolidone. Reduction of 6-cyano-6,N-dimethyl-piperidone- (2), which is prepared by the interaction of 4- acetyl butyric acid ethyl ester cyanohydrin (from the ester and hydrocyanic acid) and methylamine, yields 6,N - dimethyl - 6 - aminomethylpiperidone-(2). N, 2 - Dimethyl - 2 - methylaminomethylpyrrolidine is obtained by reducing 5-formylaminomethyl - N,5 - dimethyl - pyrrolidone - (2) which in turn is prepared by the reaction of ethyl formate with 5-methylaminomethyl-N,5- dimetbyl-pyrrolidone-(2). N - Methyl - 2 - methylaminomethyl - pyrrolidine is obtained by the reaction of N-methyl- 3-chloropiperidine with methylamine.
