Reaction Steps

To a solution of N-[4-(3-dimethylamino-propyl)-phenyl]-acetamide (0.50 mmol maximum) in methanol (8 mL) is added 20% aqueous hydrochloric acid solution. After 3½ hours of shaking at 56° C., an additional 2 drops of concentrated hydrochloric acid is added and shaking is continued for 3 days. The mixture is concentrated to give 4-(3-dimethylamino-propyl)-phenylamine hydrochloride, which is used without further purification in the following step.
