Versuchsvorschrift

0.37 g of 4-Naphthalen-1-yl-butyric acid was dissolved in 5.0 ml of toluene, and 0.35 ml of thionyl chloride and 1 drop of dimethylformamide were added, followed by heating at 70° C. for 30 minutes. The reaction solution was cooled to room temperature and concentrated under reduced pressure to give a crude 4-naphthalen-1-yl-butyryl chloride. To the resulting crude 4-naphthalen-1-yl-butyryl chloride was added 2.3 ml of a toluene solution of 0.40 g of 1-[2-(4-fluorophenyl)-2-(4-methylpiperazino)ethyl]piperazine, followed by stirring at room temperature for 30 minutes. To the reaction solution was added a saturated aqueous sodium bicarbonate solution and, after extraction with ethyl acetate, the organic layer was dried over anhydrous sodium sulfate. After removal of the drying agent by filtration, the filtrate was concentrated under reduced pressure, and the residue was purified by a silica gel column chromatography (Wako-gel C-200, chloroform:methanol=10:1) to give 0.58 g of 1-[2-(4-fluorophenyl)-2-(4-methylpiperazino)ethyl]-4-(4-naphthalen-1-yl-butyryl)piperazine as an oil.
