2-Chloro-4,6-dimethyl-5-phenyl-3-pyridinecarbonitrile (8.3 grams) was dissolved in 110 ml DMSO and treated with gaseous NH3 at a temperature of 100°-110° C. After about 66 hours of heating and treatment with NH3, the reaction mixture was cooled and poured into ice water. A solid precipitate formed which was collected, washed with water, and then dried in an oven desicator. The identity of the desired product was confirmed by NMR.
