Reaction Steps

To a mixture of 4-(6-chlorobenzothiazole-2-yl)piperazine dihydrochloride (0.50 g; 1.53 mmol), triethylamine (0.32 ml; 2.25 mmol) and anhydrous THF (10 ml) was added dropwise chloroacetylchloride (0.18 ml; 2.25 mmol) under ice-cooling. The mixture was stirred at room temperature for 24 hours. Water and ethyl acetate were added to the reaction solution and extracted. The organic layer was washed with brine, dried over anhydrous sodium sulphate, and evaporated under reduced pressure. The precipitate was washed with hexane to give 2-chloro-1-[4-(6-chlorobenzothiazole-2-yl)piperazine-1-yl]ethane-1-on as blackish brown crystal (0.15 g; 30%).
