HCID 15453186N-(3-methyl-5-isoxazolyl)-4-(4-methoxyphenyl)benzenesulfonamideYield 82%

Procedure

N-(3-methyl-5-isoxazolyl)-4-(4-methoxyphenyl)benzenesulfonamide was prepared in the same manner as described in Example 206b, using N-(3-methyl-5-isoxazolyl)-4-bromobenzenesulfonamide (Example 206a) and 4-methoxybenzeneboronic acid resulting in an 82% yield of the final product, m.p. 1 94-1 96° C. The product was recrystallized using hexane/ethyl acetate.
