실험 절차

A mixture of 3.15 g. of 3-dimethylamino-3'-(trifluoromethyl)acrylophenone and 1.40 g. of 3-aminopyrazole-4-carbonitrile in 25 ml. of glacial acetic acid is refluxed for 6 hours. The mixture is evaporated and the residue is treated as described in Example 1, giving the desired product, m.p. 144°-145° C.
