Potassium Hydroxide → HCID 13935132, compound

Participants

Reaction Steps

In 300 ml of toluene and 200 ml of 30% potassium hydroxide were added 8.00 g of 9-amino-3,4-dihydroacridin-1(2H)-one and 1.92 g of tetrabutylammonium hydrogen sulfate catalyst. The mechanically stirred biphasic solution was heated to reflux and 9.4 ml of 4-fluorobenzyl bromide in 50 ml of toluene was added dropwise. Reflux was continued for a total of 2 hours. The reaction was poured onto ice and the toluene layer was separated. The aqueous phase was extracted with ethyl acetate. The organics were combined, washed with saturated NaCl solution, dried over anhydrous magnesium sulfate, filtered and evaporated to a solid. The solid was recrystallized from 1:1 ethyl acetate/hexane to yield 5.89 g of product, mp 158°-159° C.
