Abstract
Procedure for obtaining new 4-hydroxy-piperidine derivatives, in the form of an ester of the general formula I ** (formula) ** R1 = low alkyl X = O, NH A = alkyl chain with a maximum of 3 C atoms straight chain R2 = H, halogen, O-alkyl characterized in that 1-alkyl-4-hydroxy-piperidine derivatives of the general formula II ** (formula) ** where R1 has the meaning indicated above, are reacted with reactable functional derivatives of benzoic acid of the general formula III ** (formula) ** where X, A, R2 have the meaning indicated above and Z is for chlorine or bromine or for an alkoxy group containing 1-3 C atoms.
