Water → 2-[3-[4-[2-(Dimethylamino)ethyl]phenoxy]propyl]-1H-isoindole-1,3-(2H)-dione

Participants

Reaction Steps

A mixture of 4-[2-(dimethylamino)ethyl]phenol (4.13 g) and sodium hydride (0.67 g) in dimethylformamide was stirred at room temperature for 24 h. N-(3-Bromopropyl) phthalimide (6.7 g) was added at 0° and stirring was continued for 24 h. The solution was treated with water and extracted with ether. Evaporation of the solvent gave the title compound as a white solid which was recrystallised from light petroleum (b.p. 60°-80°) 2.3 g) m.p. 81°-82°. TLC silica; ethyl acetate:water:isopropanol:0.88 ammonia 25:8:15:2; Rf 0.45.
