Abstract
A process for the preparation of new piperidine derivatives of the general formula ** (see formula) ** Or a respective quaternary ammonium or acid addition salt, wherein r represents hydrogen or lower alkyl, r1 represents hydrogen, lower alkyl, cycloalkyl with 5 to 7 carbon atoms, aryl-substituted lower alkyl or unsubstituted aryl substituted or unsubstituted (including heterocyclic aryl), or substituted or unsubstituted aroyl, ar represents a substituted or unsubstituted phenyl radical and x represents oxygen or sulfur, characterized in that a compound of the formula is reacted ** (see formula) ** Wherein r and ar have the meaning set forth for formula i, with a compound of formula iii R1n=c=x (III) In which R1 has the same meaning as for formula i except hydrogen, And x is oxygen or sulfur, and, if desired, hydrolyzing a compound of formula i, wherein r 1 is aroyl, to obtain a corresponding compound of formula i, wherein r 1 is hydrogen, or else hydrolyze or dealkylate a compound of the formula i, wherein the radical ar contains one or more substituents of lower alkoxy or aryl-lower alkoxy to obtain the corresponding compound containing one or more hydroxyl groups, and subsequently, if desired, converting, the compound of the formula i obtained in a respective quaternary ammonium or ammonium addition salt.
