Abstract
Process for the preparation of new piperidine derivatives, of the general formula I ** (See formula) ** where R 1 denotes hydrogen, an alkyl radical with at most 12 carbon atoms, an alkenyl radical with 3 to 5 carbon atoms, the cyclopropylmethyl radical or a phenylalkyl radical with 7 to 9 carbon atoms. R2 means hydrogen or the methyl radical, R3 means an alkyl radical having at most 4 carbon atoms, the phenyl radical, a phenylalkyl radical having 7 to 9 carbon atoms, the styryl radical or, together with R2, a trimethylenic radical up to hexymethylene, optionally substituted by methyl, and R4 means hydrogen or the methyl radical, and its salts with inorganic and organic acids, characterized by reacting a 4-piperidine of the general formula II ** (See formula) ** with a ketone of the general formula III R3 - CO - CH2 - R2 (III) where R1, R2, R3 and R4 have the meaning set forth above, in the presence of a basic or acidic material present in homogeneous or heterogeneous form, and by converting, if desired, into a salt with an inorganic or organic acid the compound of the general formula I obtained.
