Procedure

N-(4-bromo-3-methyl-5-isoxazolyl)-5-(3-methoxyphenyl)thiophene-2-sulfonamide was prepared in the same manner as described in Example 2 from 5-amino-4-bromo-3-methylisoxazole and 5-(3-methoxyphenyl)thiophene-2-sulfonyl chloride in 48% yield. This was purified by HPLC (5% CH3CN to 100% CH3CN over 30 min.) to give a solid.
