実験手順
A mixture of 13.7 g of 2-amino-4,5-dimethoxybenzamide, 8.1 g of triethylamine, 13.8 g of 4-chlorobenzoyl chloride and 300 ml of methylene. chloride was stirred for 2 h without cooling. The precipitate was filtered off with suction, stirred with water, filtered off with suction and dried under reduced pressure. Yield: 22.5 g. M.p.: 243° C.
