Procedure

A mixture of 4.5 g (0.035 mole) of 2,3,4-pentanetrione 3-oxime and 5.3 g (0.037 mole) of 6-chloro-3-pyridylmethylamine in 100 ml of acetonitrile was stirred at the reflux temperature for 18 hours. The reacted mixture was cooled at -10° C. with formation of a precipitate. The precipitate was washed, dried and recrystallized as for Example 24 to give 2.6 g of the desired product as a pale yellow solid, mp 239°-240° C.
