実験手順
N-(4-Methyl-3-trifluoromethyl-5-isoxazolyl)-1-naphthalenesulfonamide was prepared, as described in Example 90, from 5-amino-4-methyl-3-trifluoromethylisoxazole and 1-naphthalenesulfonyl chloride in 85% yield. Purification was achieved by recrystallization from methanol/water to give white needed, m.p. 154°-155° C.
