Participants

Reaction Steps

N-(4-bromo-3-methyl-5-isoxazolyl)-5-(4-methoxycarbonylphenyl)thiophene-2-sulfonamide was prepared in the same manner as described in Example 2 from 2-chlorosulfonyl-5-(4-methoxycarbonylphenyl)thiophene (646 mg, 2.04 mmol) and 5-amino-4-bromo-3-methylisoxazole (361 mg, 2.04 mmol). Purification by column chromatography using 10% MeOH/CHCl3 gave 384 mg of N-(4-bromo-3-methyl-5-isoxazolyl)-5-(4-methoxycarbonylphenyl)thiophene-2-sulfonamide as a brown oil (41% yield).
