Procedure

In 100 ml of dry THF was dissolved 2.47 g of 3,4-dihydro-9-(3-phenoxylpropyl)aminoacridin-1(2H)-one. The mechanically stirred solution was cooled in ice under nitrogen and 3.6 ml of 1M LiAlH4 in THF was added dropwise over 5 minutes. After 0.5 hour the reaction was complete by TLC. The reaction was neutralized with 1 ml of saturated ammonium chloride solution and the inorganic salts were filtered off. the filtrate was evaporated to an oil which recrystallized from 1:1 dichloromethane/pentane to yield after drying 2.17 g of product, mp 138°-140° C.
