Versuchsvorschrift

A mixture of 0.01 mole of 3-dimethylamino-3'-(trifluoromethyl)acrylophenone and 0.01 mole of 4-amino-5-imidazolecarbonitrile in 30 ml. of glacial acetic acid is refluxed for 6 hours. The solvent is removed under reduced pressure and worked up as for Example 29 to give the product as crystals, m.p. 168°-169° C.
