Procedure

3.4 gm of 2-amino-N-benzyl-N-tert.butyl-5-carbethoxy-benzylamine were dissolved in 50 ml of ethanol. Ethanolic hydrochlorid acid was added to the solution until a pH of about 2 was reached. The solution was then hydrogenated in the presence of palladized (10%) charcoal. After absorption of 1 mol of hydrogen, the hydrogenation was terminated, the catalyst was filtered off, the filtrate was evaporated to dryness in vacuo, and the residue was distributed between a mixture of dilute ammonia and chloroform. The chloroform phase was dried and evaporated to dryness, and the residue was recrystallized from ethanol, yielding 2-amino-N-tert.butyl-5-carbethoxy-benzylamine, m.p. 77-79° C.
