Versuchsvorschrift

In 150 ml of toluene and 700 of 30% potassisum hydroxide were combined 3.00 g of 9-amino-3,4-dihydroacridin-1(2H)-one and 0.72 g of tetrabutylammonium hydrogen sulfate. The reaction was mechanically stirred and heated with a steam bath. To it was added dropwise a solution of 13.5 g 3-trifluoromethylbenzyl bromide in 30 ml of toluene over 1 hour. After the addition, heating was continued 1 hour during which the reaction went to completion. The organic phase was separated, washed with ice-cold saturated NaCl solution, dried over anhydrous magnesium sulfate, filtered and evaporated to an oil. The oil was diluted with 10 ml of ethyl acetate and purified by preparative HPLC (ethyl acetate). The product-containing fractions were evaporated and recrystallized from DCM/hexane to yield 2.20 g of solid, mp 147°-149° C.
