Procedure

A solution of 4.1 g of cis-4-(4-nitrophenoxy)-3-phenylpiperidine hydrochloride, of Example 10, in a mixture of 125 ml of 95% aqueous ethanol and 5 ml of water is hydrogenated at 45 psi of hydrogen at room temperature over 0.41 g of 10% palladium on carbon catalyst. After 18 hours the catalyst is filtered off and the filtrate concentrated in vacuo. The resulting solid is triturated with ether and filtered to afford a nearly white salt, m.p. s 221°, 223.5°-225.5° C., of cis-4-(4-aminophenoxy)-3-phenylpiperidine hydrochloride.
