Procedure
N-(4-Methyl-3-trifluoromethyl-5-isoxazolyl)-4-biphenylsulfonamide was prepared, as described in Example 2, from 5-amino-4-methyl-3-trifluoromethylisoxazole and 4-biphenylsulfonyl chloride in 78% yield. Purification was achieved by recrystallization from ethyl acetate/hexanes to give a white solid, m.p. 139-140° C.
