Procedimiento
A process for the preparation of a compound of the formula ##STR25## which comprises (a) reacting 2-chlorobenzeneacetonitrile with 1-(2-chloroethyl)piperidine in the presence of a base and DMSO to produce a piperidinebutanenitrile of the formula ##STR26## (b) alkylating the resulting piperidinebenzene-butanenitrile with an alkylating agent in the presence of a base and DMSO to produce a piperidinebutanenitrile of the formula ##STR27## (c) hydrolyzing the resulting piperidine-butanenitrile in toluene with hydrochloric acid to produce a compound of the formula ##STR28## (d) reacting the resulting compound with isopropylamine in a solvent to form an imine of the formula ##STR29## (e) reducing the imine with sodium borohydride in ethanol to form an amine of the formula ##STR30## (f) acetylating the resulting amine with acetic anhydride in a solvent to produce an acetylated amine of the formula ##STR31## (g) hydrolyzing the acetylated amine with sulfuric acid to produce ##STR32## (h) recovering the compound so produced.
