Procedure
N-(4-Chloro-3-methyl-5-isoxazolyl)-2-biphenylsulfonamide was prepared in the same manner as described in Example 10 from 5-amino-4-chloro-3-methylisoxazole and 2-biphenylsulfonyl chloride in 74% yield. Purification was achieved by recrystallization from ethyl acetate/hexanes give a crystalline solid, m.p. 132-134° C.
