Versuchsvorschrift
N-(4-Methyl- 3-trifluoromethyl-5-isoxazolyl)-4-biphenylsulfonamide was prepared in the same manner as described in Example 2b from 5-amino-4-methyl-3-trifluoromethyl-isoxazole and 4-biphenylsulfonyl chloride in 78% yield. Purification was achieved by recrystallization from methanol/water to give a white solid, m.p. 139°-140° C.
