Procedure

In a biphasic solution comprised of 150 ml of toluene and 100 ml of 30% potassium hydroxide were added 3.00 g of 9-amino-6-chloro-3,4-dihydroacridin-1(2H)-one and 0.62 g of tetrabutylamonium hydrogen sulfate. The reaction was mechanically stirred and brought to reflux (b. p. 90° C.) with a steam bath. To the refluxing mixture was added a solution of 3.04 ml of benzyl bromide in 20 ml of toluene over 0.5 hour. Within 1 hour the reaction was complete by TLC. The toluene layer was separated and the aqueous layer was extracted with ethyl acetate. The organics were combined, dried over anhydrous magnesium sulfate, filtered and evaporated to a solid. The solid was recrystallized from dichloromethane/hexane to yield 1.63 g of a solid, mp 141°-143° C.
