A mixture of 17.7 g (52.6 mmoles) of N-(2-phthalimido-butyryl)-2,6-dimethyl-aniline, 14.2 ml of a 85% aqueous hydrazine hydrate solution and 250 ml of ethanol is boiled for one hour, and then the mixture is processed as described in Example 11. The product is triturated with petroleum ether. 9.45 g of N-(2-amino-butyryl)-2,6-dimethyl-aniline are obtained; m.p.: 48°-49° C. The product is obtained with a yield of 87.1%. The hydrochloride of the compound melts at 213°-214° C. [the melting point reported in the literature (see E. W. Byrnes et al., loc. cit.) is 213.5°-214.5° C⟧
