Reaction Steps
Ethyl piperazine-1-acetate (680 mg, 3.71 mmol) in tetrahydrofuran (8.0 mL) was mixed with triethylamine (0.776 mL, 5.57 mmol) and thiocarbonyldiimidazole (992 mg, 5.57 mmol) at room temperature and stirred at room temperate for 2 hours and then stirred with hydrazine monohydrate (0.272 mL, 5.57 mmol) for another 2 hours. The reaction solution was mixed with saturated aqueous sodium chloride and extracted with ethyl acetate. The extract was dried over anhydrous magnesium sulfate and filtered, and the filtrate was concentrated to give the crude preparation of the desired product (115% yield).
