실험 절차

A mixture of 4.86 g. of 3-dimethylamino-3'-(trifluoromethyl)acrylophenone, 50 ml. of glacial acetic acid and 2.66 g. of 3-aminopyrazole-4,5-dicarbonitrile is refluxed for 16 hours and then evaporated. The residue is treated as described in Example 1, giving the desired product, m.p. 236°-238° C.
