Abstract

Process for the preparation of new piperidine derivatives, of the general formula I ** (See formula) ** where R 1 is hydrogen, an alkyl radical having at most 12 carbon atoms, an alkenyl radical having 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 hydrogen or an alkyl radical having at most 3 carbon atoms, the phenyl radical or a phenylalkyl radical having 7 to 8 carbon atoms, and R4 means hydrogen or the methyl radical, and its salts with inorganic and organic acids, characterized in that it is a compound of the general formula II ** (See formula) ** where R1 means a radical corresponding to the given definition for R1 in claim 1 or the benzyloxycarbonyl radical, and R2, R3 and R4 has the meaning set forth above, with an aqueous mineral acid containing mercury ions, at room temperature to moderately elevated, and by dissociating a possible benzyloxycarbonylic radical R1 'by hydrogenolysis and, if desired , by becoming a salt, with an inorganic or organic acid, the compound of the general formula I obtained.
