N-(4-dimethylaminomethylphenylmethyl)acetamide → 4-Dimethylaminomethylbenzylamine

N-(4-Dimethylaminomethylphenylmethyl)acetamide (22 g) was dissolved in 4N hydrochloric acid (100 ml) and the mixture was refluxed under heating for 3 hr 40 min. The solvent was evaporated and ethyl acetate was added. The resulting crystals were collected by filtration. The obtained crystals were dissolved in water (40 ml) and potassium carbonate was added to saturation, and the mixture was extracted with chloroform. The extract was dried over anhydrous sodium sulfate and, after drying, the solvent was evaporated under reduced pressure to give the objective 4-(dimethylaminomethyl)phenylmethylamine (11.7 g), melting point 38-39° C.
