Procedure
2-[3-[3-(Formyl)phenoxy]propyl]-1H-isoindole-1,3(2H) dione (132 g) and 33% ethanolic dimethylamine (300 ml) were hydrogenated at room temperature and atmospheric pressure in ethanol over 10% palladium on charcoal. The catalyst was filtered off and the filtrate evaporated to give the title compound as a yellow oil (142 g). TLC silica (ethyl acetate) Rf 0.35, m.p. (oxalate salt) 204°-207°.
