実験手順

A mixture of 0.01 mole of 3-dimethylamino-3'-(trifluoromethyl)acrylophenone, 50 ml. of glacial acetic acid and 0.01 mole of 4-amino-2-methyl-5-imidazolecarbonitrile is refluxed for 5 hours. The solvent is removed under reduced pressure and the residue worked up as for Example 29 to give the product of the example.
