Reaction Steps
N-(4-bromo-3-methyl-5-isoxazolyl)-2-benzylbenzo[b]thiophene-3-sulfonamide was prepared by the method of Example 41 with 4-bromo-3-methyl-5-aminoisoxazole (1.0 mmoles, 0.177 g), NaH (2.5 mmoles, 100 mg), 2-benzylbenzo[b]thiophene-3-sulfonyl chloride (1.2 mmoles, 0.39 g) and THF (7 ml). Flash chromatography (5% methanol/chloroform) followed by recrystallization from chloroform and hexanes provided 0.11 g (24%) of a tan crystalline solid, m.p. 120°-123° C.
