Reaction Steps
4-Butoxy-N-(4-bromo-3-methyl-5-isoxazolyl) benzenesulfonamide was prepared from 5-amino-4-bromo-3-methylisoxazole and 4-butoxybenzenesulfonyl chloride according to the procedures described in Example 30. The crude product was purified by recrystallization from ethyl acetate/hexanes to give a crystalline solid, m.p. 98-100° C., yield 33%.
