実験手順
102 mg (0.4 mmol) of 2-amino-6-chloro-4-phenyl-3,5-pyridinedicarbonitrile [Quintela et al., Heterocycles 38, 1299-1305 (1994)] and 54 mg (0.48 mmol) of potassium tert-butoxide are dissolved together in 1.696 g (=1.5 ml, 15.55 mmol) of 2-hydroxymethylpyridine, and the mixture is stirred at 60° C. for about 16 h. The product which crystallizes out is filtered off with suction, washed with water and dried under reduced pressure.
