Versuchsvorschrift
N-(4-Ethyl-3-trifluoromethyl-5-isoxazolyl)-1-naphthalenesulfonamide was prepared, as described in Example 90, from 5-amino-4-ethyl-3-trifluoromethylisoxazole and 1-naphthalenesulfonyl chloride in 70% yield. Purification was achieved by recrystallization from methanol/water to give an off white solid, m.p. 135°-137° C.
