    • 1304415 Preparation of 17α-hydroxy or acyloxyandrostane compounds ORGANON LABORATORIES Ltd 1 April 1970 [8 April 1969] 15371/70 Heading C2U A 17α-acyloxy or 17α-hydroxy steroid is prepared by reacting a 17#-sulphonyloxy steroid, derived from any organic sulphonic acid, with an alkali metal salt of a C 1-6 aliphatic carboxylic acid in the presence of a C 1-6 aliphatic carboxylic acid and an aprotic solvent and, when required, hydrolysing the 17α-acyloxy steroid first formed to the free 17α-hydroxy steroid. Suitable starting materials are sulphonates of testosterone, 19-nortestosterone, estradiol, 17#-dihydroequilin and 17#-dihydroequilenin. The sulphonyloxy steroids can for example be derived from alkyl-, aryl- or aralkyl-sulphonic acids. If the alkali metal salt reagent is derived from an acid different from the free acid reagent used then a mixture of different 17α-acyloxy products is formed. The preferred solvent is dimethylformamide.

Novel fused-ring piperazine derivatives of the general formula wherein R 1 and R 3 are each a hydrogen or halogen atom, a hydroxy, C 1-6 acyloxy, C 1-6 alkyl, C 1-6 alkoxy or trifluoromethyl group; R 2 is a hydrogen atom or a C 1-6 alkyl or aralkyl group, or an aminoethyl or aminopropyl N- substituted by one or more C 1-6 alkyl groups, or a C 1-6 alkyl group attached to a N-containing heterocyclic ring, said ring being directly bonded to the N atom of the piperazine ring; and P is a single bond or a methylene, ethylene or -CH= CH- group; and acid addition salts thereof are prepared by reduction of the corresponding piperazinones having keto groups in at least one of the positions 3, 5 and 6 of the piperazine ring, followed by optional conversion to an acid addition salt of the product. The piperazinone starting materials are prepared (a) by reaction of an amine of the formula with a compound of the formula wherein X is a halogen or a C 1-6 alkoxy group and Z is two hydrogen atoms or an oxygen atom, to give a 5-keto-, 6-keto- or 5,6-diketopiperazine derivative; or (b) by reaction of an amine of the second formula above, wherein R 2 is hydrogen with benzyl chloroformate, followed by reaction of the product with a halogenated acetic acid halide, removal of the benzyloxycarbonyl group by catalytic reduction and closure of the piperazine ring at an elevated temperature. 6 - Chloromethyl - morphanthridine and 2 - bromo - 6 - chloromethyl - phenanthridine are prepared by ring closure methods from N- chloroacetyl - 2 - benzylaniline and N - chloroacetyl - 2 - phenyl - 4 - bromoaniline, respectively. 6 - Cyanodibenzo - (b,f) - azocine is prepared by reaction of 6-chlorodibenzo-(b,f)- azocine with sodium cyanide. 6-Formylaminomethyl - 5,6 - dihydro - dibenzo - (b,f) - azocine is prepared by the action of methyl formate on 6 - aminomethyl - 5,6 - dihydrodibenzo - (b,f)- azocine. Pharmaceutical compositions having antiinflammatory, -serotoninic, -histaminic and -phlogistic activity comprise a fused-ring piperazine derivative of the first formula above or an acid addition salt thereof as active ingredient, together with at least one pharmaceutical carrier.
