実験手順

A mixture of 13.1 g of 3,5-dimethylanthranilamide and 13.1 g of 2-bromothiazole was heated for 30 minutes at 155° C. and stirred for 12 hours. After the mixture had cooled to 25° C., the pH was adjusted to 9 by adding water and 25% strength ammonia solution, while stirring, and the resulting solution was stirred for 10 minutes. The solution was then suction filtered and the filtrate was washed with methanol and dried, 10.5 g of the above compound was obtained; m.p. 190°-192° C. The methanol filtrate was concentrated, taken up in ethyl acetate and chromatographed over aluminum oxide. After concentration a further 4.4 g of the above compound were obtained; total yield: 81%.
