Reaction Steps

4-[3-(5-Isoxazol-3-yl-thiophene-2-sulfonylamino)-benzoylamino]-benzoic acid, MS (ISP): m/e=468.1 (M−H), was prepared in analogy to example 1, steps A to D. Step C was performed using 5-isoxazol-3-yl-thiophene-2-sulfonyl chloride and yielded 4-[3-(5-isoxazol-3-yl-thiophene-2-sulfonylamino)-benzoylamino]-benzoic acid ethyl ester, which was hydrolyzed in step D.
