实验步骤: 2-Iodobenzohydrazide (1.38 g, 5.27 mmol) obtained in Step 1 of Example 114 was dissolved in dichloromethane (50 mL), and the mixture was stirred at 0° C. for 1.5 hours after adding pyridine (0.639 mL, 7.90 mmol) and acetyl chloride (0.412 mL, 5.79 mmol). The precipitated solid was filtered off, and the resulting solid was dried under reduced pressure to give N′-acetyl-2-iodobenzohydrazide (1.23 g, 77%). The precipitated solid was filtered off the resulting solid was dried under reduced pressure

实验步骤: 2-Iodobenzoic acid (3.00 g, 12.1 mmol) was dissolved in dichloromethane (150 mL), and the mixture was stirred at room temperature for 2 hours after adding 1,1′-carbonyldiimidazole (2.16 g, 13.3 mmol). Thereafter, hydrazine.monohydrate (3.52 mL, 72.6 mmol) was added to the mixture, and the mixture was stirred at room temperature for 3 hours. Water was added after concentrating the mixture under reduced pressure, and the precipitated solid was collected by filtration, and dried under reduced pressure to give 2-iodobenzohydrazide (2.81 g, 89%). the mixture was stirred at room temperature for 3 hours after concentrating the mixture under reduced pressure the precipitated solid was collected by filtration dried under reduced pressure
