Methyl 4-bromobenzoate → 4-Bromobenzohydrazide

Participants

Reaction Steps

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