Reaction Steps

A solution of phenyl (4-piperidinyl)methanone (18.1 g, 0.096 mol) was dissolved in toluene (200 ml) containing 1-bromo-3-phenylpropane (21.9 g, 0.11 mol, 16.7 ml), K2CO3 (30.4 g, 0.22 mol) and KI (0.2 g) and was refluxed for 64 h. The reaction mixture was filtered and concentrated to give a light yellow oil. This material was dissolved in toluene/EtOAc (1:1) and treated with HCl (0.096 mol) dissolved in CH3OH/EtOAc (2:5, 35 ml) to give a precipitate which was filtered off and recrystallized twice from EtOH/Et2O (150 ml) to give phenyl[1-(3-phenylpropyl)-4-piperidinyl]-methanone hydrochloride, mp 199°-200° C.
