실험 절차

A solution of 1.0 g. of 2,2,2-trifluoro-N-[5 -phenyl-1-(p-trifluoroacetylphenyl)-2-pyrazolin-3-yl]acetamide (prepared as described in Example 9) in 100 ml. of methanol is saturated with ammonia gas, then is stored in a refrigerator for 16 hours. The solution is evaporated to dryness in vacuo. The residue is chromatographed by preparative column chromatography using silica gel and eluting with acetone:hexane, 50:50, to collect the most polar product. The product is recrystallized from dichloromethanehexane to yield 0.25 g. of the product of the Example as yellow needles, m.p. 214°-216° C.
