Abstract

1,178,624. Piperidine derivatives. SANDOZ Ltd. 10 April, 1967 [10 May, 1966; 8 March, 1967 (3)], No. 42730/69. Divided out of 1,178,623. Heading C2C. Compounds of the Formula (III) in which either each of R 3 and R 4 is 1-4 C- alkyl, or R 3 and R 4 together with N- form a pyrrolidine, piperidine, morpholine, or N- methylpiperazine radical and R 5 is H or R 3 is 1-4 alkyl and R 4 and R 5 together form -CH 2 -CH 2 -, and their acid addition salts are prepared by reacting a compound of the Formula (IV) with 1-benzyl-4-piperidone in an inert solvent in the presence of an alkali metal amide, decomposing the complex formed by hydrolysis and submitting 1-benzyl-derivative to hydrogenolysis.
