Reaction Steps

To a solution of 2-bromobenzohydrazide (500 mg, 2.3 mmol) in methanol (5 mL) was added phenyl isocyanate (280 mg, 2.4 mmol) at room temperature, and then the mixture was refluxed for one hour. The reaction mixture was cooled to room temperature. The precipitated solid was filtered off and dried under a reduced pressure to give 370 mg (48%) of the titled compound as a colorless solid.
