Procedure: N-Acryloyl-4-fluoroaniline (12.2 g) and 1-benzyl piperazine (19.7 g) were dissolved in methanol (150 ml), and the mixture was stirred overnight at room temperature. The reaction mixture was evaporated, and the residue was purified by Cromatorex NH silica gel column chromatography (hexane/ethyl acetate system) to give the title compound (25 g, 100%) as a colorless oil. The reaction mixture was evaporated the residue was purified by Cromatorex NH silica gel column chromatography (hexane/ethyl acetate system)

Procedure: 4-Fluoroaniline (7 ml) and acryloyl chloride (7.2 ml) were dissolved in tetrahydrofuran (100 ml), then triethylamine (15 ml) was added thereto, and the mixture was stirred overnight at room temperature. The organic layer was partitioned by adding aqueous saturated sodium bicarbonate and ethyl acetate, and the organic layer was washed with water and dried over sodium sulfate anhydrous, and after the drying agent was filtered off, the filtrate was evaporated, whereby the title compound (12.2g, 100%) was obtained as pale yellow solid. The organic layer was partitioned by adding aqueous saturated sodium bicarbonate and ethyl acetate the organic layer was washed with water dried over sodium sulfate anhydrous after the drying agent was filtered off the filtrate was evaporated
