Reaction Steps

9.7 g of 7-methoxycarbonylbenzo-1,2,3-thiadiazole are reacted for 19 hours with 4.8 g of hydrazine hydrate in 30 ml of water at 50° C. and then for a further 6 hours at 80°-90° C. The suspension is cooled slightly, filtered while hot and washed with water to give 8.8 g of white crystals having a melting point of 270°-272° C.
