实验过程

6-Fluoro-3-(2-propenyl)-2(3H)-benzothiazolon-5-yl isocyanate (1.99 g) and ethyl hexahydropyridazine-1-carboxylate (1.26 g) were added to toluene (8 ml). A catalytic amount of triethylamine was added thereto, and the resultant mixture was stirred at 25° C. for 12 hours. Water was added thereto, and the resultant mixture was extracted with toluene. The extract was washed with water, dried and concentrated to give ethyl 2-[6-fluoro-3-(2propenyl)-2(3H)-benzothiazolon-5-ylaminocarbonyl]-hexahydropyridazine-1-carboxylate (2.26 g). m.p., 161.2° C.
