Diethyl Ether → 8-Methoxy-1,2,3,4-tetrahydro-9-acridinamine

6-Methoxyanthranilonitrile (14.0 g) was dissolved in nitrobenzene (150 ml) and cyclohexanone (18.45 g), and freshly fused zinc chloride (25.6 g) was added. The reaction mixture was warmed at 125° C. for 1.5 hr, cooled to room temperature, and poured into ether (1 l). The solid was collected, washed with ether, and distributed between 2-butanone and ammonium hydroxide. The organic phase was washed with brine, dried, filtered, and evaporated. The residue was recrystallized two times from ethyl acetate to give 13.7 g (63.8%), mp 187°-188° C.
