Reaction Steps

N-(4-bromo-3-methyl-5-isoxazolyl)-2-(4-ethylbenzyl)benzo[b]-thiophene-3-sulfonamide was prepared by the method of Example 41 using 4-bromo-3-methyl-5-aminoisoxazole (1.0 mmoles, 0.177 g), NaH (2.5 mmoles, 100 mg), 2-(4-ethylbenzyl)benzo[b]thiophene-3-sulfonyl chloride (1.2 mmoles, 0.42 g) and THF (6 ml). Flash chromatography (50% ethyl acetate/hexanes) followed by recrystallization from chloroform and hexanes provided 0.21 g (43%) of a tan solid, m.p. 128-130° C.
