Procedure

In 100 ml dry THF was dissolved in 3.86 g of 3,4-dihydro-9-(3-trifluoromethylbenzyl)aminoacridin-1(2H)-one. The solution was stirred mechanically under nitrogen and cooled in ice. To it was added 5.2 ml of 1M LiAlH4 in THF dropwise. After stirring an additional 0.5 hour, the reaction was complete. It was neutralized with 1 ml of saturated ammonium chloride and the salts were filtered off. The THF filtrate was evaporated to an oil which solidified upon trituration with pentane. The solid was recrystallized from 1:1 dichloromethane/pentane to yield 3.12 g of solid, mp 154°-155° C.
