Reaction Steps

In a mixture consisting of 150 ml of dichloromethane and 100 ml of 50% NaOH were combined 5.00 g of 9-amino-3,4-dihydroacridin-1(2H)-one, 3 ml (1 eq) of 2-fluorobenzylchloride and 1.20 g (0.15 eq) of tetrabutylammonium hydrogen sulfate. The biphasic mixture was mechanically stirred overnight and 3 ml of 2-fluorobenzylchloride was again added. After 4 hours of further stirring, the reaction was complete based on thin layer chromatography. The reaction mixture was partitioned between water and dichloromethane and the dichloromethane layer was separated, dried over MgSO4, filtered and evaporated to a solid. The solid was purified by chromatography on silica gel (EtOAc) and the resultant product was recrystallized from 1:4 EtOAc/toluene to yield 4.09 g (54%) of a solid, melting point 163.5°-164° C.
