A mixture of 3.7 g. (0.01 mole) of 2,4-bis(2,4,4-trimethyl-2-pentylamino)-6-chloro-s-triazine, 2.6 g. (0.02 mole) of 2,4,4-trimethyl-2-pentylamine and 2,85 g. (0.03 mole) of α-pyridone are fused and heated at the boiling point for 21/2 hours during which time the mixture turns a brown color. At the end of this period the mixture is cooled yielding a solid mass which is treated with about 10 ml. of 10% sodium hydroxide. On filtration, 4.52 g. of a beige solid is obtained m.p. 151°-156° C. Recrystallization of the beige solid from 75 ml. of hot ethanol yields 3.09 g. of colorless needles, m.p. 156°-157.5° C.
