실험 절차

5-Bromo-2-methoxy-N-(4-bromo-3-methyl-5-isoxazolyl)benzenesulfonamide was prepared from 5-amino-4-bromo-3-methylisoxazole and 5-bromo-2-methoxybenzenesulfonyl 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. 192-195° C., yield 61%.
