Ethanol → m-Bromobenzohydrazide

Participants

Reaction Steps

First, 10 g (44 mmol) of ethyl-3-bromobenzoate was put in a 200-mL three-neck flask, 50 mL of ethanol was added therein, and the mixture was stirred. Thereafter, 12 mL of hydrazine monohydrate was added therein, and the mixture was stirred at 78° C. for 5 hours so as to be reacted. After the reaction, water was added to the reaction solution, and a solid was precipitated. The precipitated solid was collected by suction filtration. The obtained solid was put in approximately 500 mL of water, washed, and again collected by suction filtration; thus, 8.1 g of a white solid that was an object was obtained (yield: 86%).
