Procedure
2-[3-[4-[2-(Dimethylamino)ethyl]phenoxy]propyl]-1H-isoindole-1,3-(2H)-dione (2.1 g) and hydrazine hydrate (1.2 ml) were heated at reflux in ethanol for 4 h. The solvent was evaporated and the residue was distilled to give the title compound as a clear yellow oil b.p. 170° (0.1 mm). TLC silica; ethyl acetate:water:isopropanol:0.88 ammonia 25:8:15:2; Rf 0.35.
