Versuchsvorschrift

A mixture of 6.5 g (0.05 mole) of 2,3,4-pentanetrione 3-oxime and 6.0 g (0.055 mole) of 2-pyridylmethylamine in 125 ml of acetonitrile was stirred and refluxed as described in Example 1. Cooling at -10° C. gave a precipitate which was recrystallized from acetonitrile to give 3.6 g of the product of the Example as a yellow solid, mp 145°-147° C.
