Abstract

The invention comprises esters of the general formula :- <FORM:0847051/IV(b)/1> and acid addition salts thereof wherein R is a phenyl or naphthyl or a nitro and/or a methoxy phenyl radical and a process for the manufacture thereof whereby 5-(11-methyl-piperidyl-41)-pentanol-2 with an appropriate benzoic or naphthoic acid halide and, if desired, converting the resulting ester hydrohalide into the free ester by treatment with a base or into a further acid addition salt by cationic exchange or treatment with a base followed by treatment with an acid. 5-(11-Methyl-piperidyl-41)-pentanol-2 and its hydro-bromide is prepared by reacting 4-vinyl-pyridine with sodio ethyl acetoacetate to give ethyl 2 - acetyl - 4-(pyridyl-41)-butyrate (and its picrate) which is subjected to alkaline hydrolysis to give 5-(pyridyl-41)pentanone-2 this in turn is reduced to 5-(pyridye-41)-pentanol-2 (and its hydrobromide) either by lithium aluminium hydride, hydrogen in the presence of Raney-nickel, or potassium boron hydride, and the alcohol is quaturnised with methyl bromide and reduced by hydrogen and Raney-nickel.
