Procedure: 270 Parts of tetrahydrofuran were added carefully to 10 parts of lithium tetrahydroaluminate. A solution of 66 parts of ethyl 1-(phenylmethyl)-4-piperidinepropanoate in 180 parts of tetrahydrofuran was added dropwise to the thus obtained mixture (exothermic reaction, the temperature rose to about 45° C.). The whole was stirred overnight at reflux temperature. The mixture was cooled in an ice salt bath and decomposed at 0° C. with successively 10.5 parts of water, 7.8 parts of a sodium hydroxide solution 20% and 33.8 parts of water. The mixture was filtered over diatomaceous earth and the filtrate was evaporated, yielding 56 parts (100% of 1-(phenylmethyl)-4-piperidinepropanol as a residue (int. 40). exothermic reaction rose to about 45° C. at reflux temperature The mixture was cooled in an ice salt bath The mixture was filtered over diatomaceous earth the filtrate was evaporated
