Reaction Steps

A mixture of 4-fluorobenzoic acid ethyl ester (1.25 g), 1-[4-(4-phenylpiperidin-1-yl)phenyl]piperazine (1.19 g) and potassium carbonate (1.53 g) in dimethylsulfoxide (18 ml) was stirred for 12 hours at 150° C. The reaction mixture was pulverized with water. The mixture was extracted with dichloromethane. The organic layer was separated, washed with brine, dried over magnesium sulfate. The magnesium sulfate was filtered off, and the filtrate was evaporated under reduced pressure. The residue was purified by column chromatography over silica using dichloromethane/methyl alcohol (200:1) as the elution. The powder was recrystallized from toluene (60 ml). The crystal was collected by filtration, and dried under reduced pressure to give 4-[4-[4-(4-phenylpiperidin-1-yl)phenyl]piperazin-1-yl]benzoic acid ethyl ester (0.80 g).
