Reaction Steps

A mixture of 16 g of 2-chloro-4-(4-fluorophenyl)quinoline and 25.4 g of 1-(2-hydroxyethyl)piperazine is stirred at 130° C. for 3 hours. After cooling, water is added and the resulting mixture is extracted with ethyl acetate. The organic layer is dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue is chromatographed on silica gel (150 g) with chloroform - methanol (100 : 1). The eluates pooled are concentrated to give an oily residue, which is treated with ethanolic hydrogen chloride to afford the hydrochloride. Recrystallization from ethanol - ethyl acetate gives 16.7 g of the title compound, m.p. 210°-218° C.
