실험 절차

A four neck flask (1 liter) equipped with a thermometer, a reflux condenser and a stirrer was charged with 68.0 g (0.5 mol) of benzohydrazide, 700 ml of methanol and 3.5 ml of acetic acid. Added thereto was 109.2 g (0.6 mol) of benzophenone while stirring at room temperature, and heating under reflux was continued for 12 hours. The reaction liquid was cooled down to 5° C. or lower, and then crystal was filtered off and dried under reduced pressure, whereby white crystal was obtained.
