The mixture consisting of 1.8 g of 2-nitrobenzoic hydrazide, 1.6 g of 2-methylbenzo[d][1,3]oxazin-4-one and 5 ml of N-methylpyrrolidone was heated to 80° C. with stirring for 2 hours. After cooling, the mixture was admixed with water to slight cloudiness and stirred for a further 1 hour, during which time a solid precipitated out which was filtered off with suction, recrystallized from ethanol and dried under reduced pressure.
