Abstract

Procedure for obtaining alpha-alanil-2,6-dimethyl-aniline and beta-alanil-2,6-dimethyl-aniline. The synthesis of these derivatives is carried out in five steps. The first step consists of the protection of the amino group of alpha- or beta-alanine with ftalic anhydride to give the corresponding ftaloil-alanine. The second step consists of the formation of the acid chloride of the relevant ftaloil-alanine, which is carried out with a chloride of tionilo to reflux. Eliminating the excess of chloride is obtained the corresponding acid chloride. The third phase consists of the reaction of the corresponding chloride of ftaloyl-alanine with 2,6-dimethyl-aniline in a dioxane medium. A precipitate of ftaloil-alanil-2,6-dimetilanilin is obtained. The fourth phase of the process is the unlocking of the group used to protect the amino group from alanina in the first step and, finally, the last step consists in the formation of the corresponding alyan-2,6-dimethylaniline hydrochloride.
