Conditions
- Temperature
- 5 °C
Procedure
A four neck flask (1 liter) equipped with a thermometer, a reflux condenser and a stirrer was charged with 136 g (1.0 mol) of benzohydrazide and 600 ml of acetone and then heated under reflux 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.
