Procedure

N-(4-Bromo-3-methyl-5-isoxazolyl)-4-toluenesulfonamide was prepared from 5-amino-4-bromo-3-methylisoxazole and 4-toluenesulfonyl chloride according to the procedures described in Example 40b. The crude product was purified by recrystallization from ethyl acetate/hexanes to give off-white crystals, m.p. 169°-172° C., yield 69%.
