Participants

Reaction Steps

A mixture containing 0.15 g. of 3-[4-(diethylamino)benzoyl]-2-pyrazinecarboxylic acid, 0.18 g. of 4,4'-dioctyldiphenylamine and 3 ml. of acetic anhydride was gently heated for 5 hours and then allowed to stand overnight. The product, 7-[4-(diethylamino)phenyl]-7-[bis(4-octylphenyl)amino]furo-[3,4-b]pyrazine-5(7H)-one was isolated by column chromatography followed by crystallization from hexane to give a peach solid, m.p. 180°-181° C. A toluene solution of this product contacted with acidic clay or phenolic resin developed a red image.
