Reaction Steps

3-Cyano-4,6-dimethyl-5-phenyl-2-pyridone (7.0 grams) and phenylphosphonic dichloride (12.1 grams) were heated at 175°-180° C. for 2-3 hours. The solution was cooled, poured into ice water and made basic with ammonium hydroxide. A precipitate formed which was collected, air dried, and determined by NMR to be the desired product, yield 7.6 grams, m.p. 118°-123° C.
