Reaction Steps
A mixture of 22.8 g (0.05 mole) of 4-[4-(α-hydroxy-α-phenylbenzyl)piperidino]-1-(2-thienyl)butan-1-one hydrochloride, 500 ml of isopropyl alcohol and 500 ml of concentrated HCl was heated on a steam bath for 3 hours, and the solvent was removed under vacuum. Isopropyl alcohol and 300 ml of water were added to the residue and heated to 80° C. Upon cooling a precipitate formed which was collected and recrystallized from methanol-ethyl acetate and toluene to give the desired product, M.P. 132.5°-134.5° C.
