Mode opératoire

N-(4-chloro-3-methyl-5-isoxazolyl)-2-(4-dimethylaminobenzyl)benzo[b]thiophene-3-sulfonamide was prepared by the method of Example 41 with 4-chloro-3-methyl-5-aminoisoxazole (0.52 mmoles, 69 mg), NaH (1.3 mmoles, 31 mg), 2-(4-dimethylaminobenzyl)-benzo[b]thiophene-3-sulfonylchloride (0.58 mmoles, 0.21 g) and THF (4 ml). Flash chromatography (5% methanol/chloroform) provided 0.16 g (66%) of a yellow gummy solid, m.p. 105-110° C.
