4,6-Dimethyl-5-phenyl-2-pyridylamine (0.5 gram) was dissolved in 25 ml acetonitrile and reacted with 2-chlorobenzoyl isocyanate (0.6 gram) under nitrogen at room temperature. A precipitate formed immediately and the reaction was stirred for approximately 2 hours. The solid product was collected, washed with a small amount of acetonitrile, and identified by NMR as the desired product, m.p. 176°-189° C.
