참여 물질

반응 단계

1-Hydroxybenzotriazole (HOBt) (270 mg, 2 mmol) and 1-(3-(dimethylamino)propyl)-3-ethylcarbodiimide hydrochloride (WSC) (498 mg, 2.6 mmol) were added to a solution of 3-acetamino-4-methoxycarbonylbenzoic acid (474 mg, 2 mmol) in dimethylformamide (10 mL), and the mixture was stirred at room temperature for 3 hours. Hydrazine monohydrate (485 μL, 10 mmol) was further added at 0° C., and the mixture was stirred overnight at room temperature. The precipitated solid was filtered, and then washed with water to obtain 400 mg of the desired product as a white solid (yield 80%).
