Reaktionsschritte

N-(4-Tridecyl-3-trifluoromethyl-5-isoxazolyl)-4-biphenylsulfonamide was prepared, in the same manner as described in Example 2b, from 5-amino-4-tridecyl-3-trifluoromethyl-isoxazole and 4-biphenylsulfonyl chloride in 81% yield. Purification was achieved by recrystallization from methanol/water to give an off white solid, m.p. 115°-116° C.
