Participants

Reaction Steps

N-(4-bromo-3-methyl-5-isoxazolyl)-5-(benzyloxymethyl)thiophene-2-sulfonamide was prepared as described in Example 2 from 2-chlorosulfonyl-5-(benzyloxymethyl)thiophene (520 mg, 1.72 mmol) and 5-amino-4-bromo-3-methyl isoxazole (319 mg, 1.8 mmol). Purification by column chromatography using 10% MeOH/CHCl3) gave 238 mg of pure N-(4-bromo-3-methyl-5-isoxazolyl)-5-(benzyloxymethyl)thiophene-2-sulfonamide as brown semisolid (31% yield, m.p. 92° C.).
