실험 절차

To a cooled solution of 5.7 g of 3,4-dihydro-6-fluoro-9-(2-trifluoromethylbenzylamino)acridin-1(2H)-one in 80 ml of tetrahydrofuran was added 7.5 ml of 1 molar solution of lithium aluminium hydride in THF. This was stirred for 0.5 hour and then quenched with 6 ml of saturated ammonium chloride solution. The inorganics were filtered, rinsed with ethyl acetate and the combined organics were dried over anhydrous magnesium sulfate. This was concentrated to a solid which was triturated with ether to give 5.1 g of a powder. This was twice recrystallized from ethyl acetate/hexane to give 3.1 g of analytically pure crystals, mp 149°-153° C.
