Reaction Steps
According to the method of intermediate 46, 4-fluorobenzenesulfonic acid 2-isobutyrylaminobenzothiazol-6-yl ester is prepared via the action of 4-fluorobenzenesulfonic acid 2-aminobenzothiazol-6-yl ester (intermediate 16, brevetbenzothiazole_V2) with isobutyric acid. The crude reaction product is crystallized from ethyl ether and, after filtering off by suction, 0.17 g of colorless solid is isolated, i.e. an 86% yield.
