실험 절차

A mixture of 5.0 g. of 3-amino-1-phenyl-2-pyrazoline (prepared as described in Example 8), 200 ml. of dichloromethane, 5.0 ml. of triethylamine and 7.0 ml. of trifluoroacetic anhydride is allowed to remain at room temperature for 30 minutes. The mixture is evaporated to dryness in vacuo, then water is added to separate a semi-solid. The solid is dissolved in dichloromethane. The solution is dried over anhydrous sodium sulfate, columnized and recrystallized as for Example 14 (B) to give 3.0 g. of the desired product as yellow-orange prisms, m.p. 163°-165° C.
