Procedure

2-(4-Fluorophenyl)-N-(4-piperidinyl)acetamide (WO97/36871; 0.05 g), 2-quinolinecarbaldehyde (0.033 g) and sodium triacetoxyborohydride (0.067 g) in dichloroethane (3 ml) were stirred under nitrogen for 24 hours. Saturated sodium hydrogen carbonate was added to the reaction, with the resulting solution being extracted three times with dichloromethane. The pooled organic phases were washed once with water, once with brine, dried over magnesium sulfate, filtered and the solvent removed under reduced pressure, triturated with diethyl ether/ethyl acetate and filtered to leave 2-(4-fluorophenyl)-N-[1-(2-quinolinylmethyl)-4-piperidinyl]acetamide (0.020 g).
