First, 3.0 g (13.9 mmol) of methyl-4-bromobenzoate was put in a 100-mL three-neck flask, 10 mL of ethanol was added thereto, and the mixture was stirred. Thereafter, 4.0 mL of hydrazine monohydrate was added thereto, and the mixture was heated and stirred at 78° C. for 5 hours. The obtained solid was washed with water and collected by suction filtration; thus, 2.0 g of a white solid of 4-bromobenzohydrazide that was an object was obtained in the yield of 67%.
