Procedure

While stirring a mixture comprising 195 mg of 4-hydroxyacridine (20), 214 mg of 2-amino-5-diethylaminotoluene hydrochloride (21) and 6.8 ml of ethanol at 20° C., a solution comprising 0.17 mg of silver nitrate dissolved in 0.75 ml of water was added thereto drop-by-drop. Next, with 0.85 ml of 25% ammonia solution added to the mixture, reaction was allowed to proceed at 20° C. for a period of 24 hr. After the completion of the reaction, the reacted solution was introduced into water. After extraction by ethyl acetate, the extract was concentrated. After purification by column chromatography, 72.5 mg of indoaniline derivative (25) described in the exemplified compound 4-1 was obtained as deep blue crystals on recrystallization by hexane-ethyl acetate (yield 19.6%).
