To a suspension of 4-piperazin-1-yl-benzoic acid ethyl ester dihydrochloride (1 g) and potassium bicarbonate (1.57 g) in acetonitrile (10 ml) was added methanesulfonic acid indane-2-yl ester (0.69 g) and the mixture was stirred under refluxing for 8 hours. The reaction mixture was pulverized with water. The precipitate was collected by filtration and dried over under reduced pressure. The powder was purified by column chromatography on silica gel using methanol/dichloromethane (50:1) as the eluent to give 4-(4-indan-2-yl-piperazin-1-yl)benzoic acid ethyl ester (0.38 g).
