Procedure

A 2.0 g. amount of 3-amino-1-phenyl-2-pyrazoline (Example 1) is dissolved in 15 ml. of concentrated hydrochloric acid, then is poured into anhydrous ethyl ether to crystallize a product. The product is collected by filtration and recrystallized from acetone-hexane to give 1.50 g. of the desired product as a white solid, m.p. 94°-96° C.
