실험 절차

A combination of 10 g Intermediate B and 8 g N,N-diphenylformamidine was thoroughly mixed and heated with stirring at 150°-160° C. for 25 minutes. The flask was then fitted with a condenser and 50 ml hot acetone was cautiously added. An orange precipitate formed. The flask was removed from the heat, cooled, and chilled in ice. After 1 hour, the reddish precipitate was filtered off and discarded. The filtrate was poured into 300 ml diethyl ether and stirred for 2 hors. The resulting yellow-orange powder was filtered, washed with ether, and dried to yield 10.6 g of 2-(2-anilinovinyl)-3-ethyl-5-hexylsulfonamidobenzoxazolium p-toluenesulfonate (Intermediate C).
