Esters of heterocyclic γ-amino alcohols

The benzoic (III-IX) and the p-nitrobenzoic (X-XVI) esters were prepared by the action of the acid chloride of benzoic and p-nitrobenzoic acids on the lithium alcoholate of 1,2,5-trimethyl-5-aminomethyl-4phenylpiperidin-4-ols (iI) made by the reaction of phenyllithium with 1,2,5-trimethyl-5-aminomethylpiperid-4-ones (i). Some esters were also prepared by… CONTINUE READING
