A mixture containing 3.1 g. of 3-[4-(diethylamino)-2-methylbenzoyl]-2-pyrazinecarboxylic acid, 3.1 g. of 4,4'-dioctyldiphenylamine and 25 ml. of acetic anhydride was stirred in a warm water bath for 3 hours. The reaction mixture was poured into water and the resulting solid was collected and recrystallized from hexane to give 7-[4-(diethylamino)-2-methylphenyl]-7-[bis(4-octylphenyl)amino]furo[3,4-b]pyrazine-5(7H)-one as a light tan solid, m.p. 180°-187° C. A toluene solution of this product contacted with acidic clay or phenolic resin developed a violet image.
