실험 절차
A mixture of 2.0 g. of 3-amino-5-methyl-1-phenyl-2-pyrazoline (prepared in Example 5), 5.0 ml. of acetic anhydride and 100 mg. of 4-dimethylaminopyridine is allowed to stand at room temperature for 3 hours. The mixture is filtered to give a white solid. The solid is dissolved in dichloromethane and is columnized and recrystallized as for Example 14 (B) to give 0.90 g. of the desired product as colorless plates, m.p. 144.5-146.5° C.
