Abstract
Process for the production of piperidine derivatives, of formula I, **(See formula)** where n is 1, 2 or 3, R1 is lower alkyl, R2 is hydrogen or lower alkyl, R3 is hydrogen, chlorine, bromine, fluorine, trifluoromethyl, lower alkyl, lower alkoxy or lower alkylthio, A and B together with double bond form a benzene ring, or a benzene ring substituted by chlorine, bromine, fluorine, trifluoromethyl, lower alkyl, lower alkoxy or alkylthio: lower, or A is sulfur and A and B together form a thiophene ring, or a thiophene ring substituted in the α position with respect to sulfur by chlorine, bromine or lower alkyl, and Y is ethylene or vinylene, when A and B together with the double bond form a benzene ring, or a benzene ring substituted by chlorine, bromine, fluorine, trifluoromethyl, lower alkyl, lower alkoxy or lower alkylthio, or when A is sulfur and A and B together with the double bond form a thiophene ring, or a thiophene ring substituted in the α position with relation to sulfur by chlorine, bromine or lower alkyl r, or Y is oxygen, methyleneoxy, methylenethio or a group (see formula), where R4 and R5 are independently lower alkyl, when A and B together with the double bond form a benzene ring, or a benzene ring substituted by chlorine, bromine, fluorine, trifluoromethyl, lower alkyl, lower alkoxy or lower alkylthio, or Y is sulfur, when A is sulfur and A and B together with the double bond form a thiophene ring, characterized in that a compound of formula II is alkylated, **(See formula)** where A, B, Y and R3 have the meanings indicated above, with a compound of formula III, Z-CO-R1 III where R1 has the meaning indicated above, and Z is a) X- (CH2) n-CHR2-, where R2 and n have the meanings indicated above, and X is the acidic radical of a reactive ester, to produce a compound of formula I, or b) CH2 = CR2-, where R2 has the meaning indicated above, to produce a compound of formula I, where n is 1.
