Procedure

A 6.0 g. amount of 3-amino-4-methyl-1-phenyl-2-pyrazoline (Example 4) and 12.0 ml. of methyl iodide is heated at reflux for 2 hours. The reaction mixture is cooled and filtered to collect 11.2 g. of crude product. The material is dissolved in water and recrystallized from 95% ethanol to give 4.5 g. of the product of the Example as colorless needles, m.p. 168.5°-170° C.
