Abstract
FIELD: preparation of aminoacids, more particularly preparation of n-aminomethylbenzole acid used for synthetizing drugs. SUBSTANCE: in order to make the process simpler and cheaper, cyanobenzoic acid methyl ester is carried out electrochemically on cathode formed of negatively charged plates of lead storage battery in the other solvents such as mixture of isopropanol, water and concentrated HCl [(volumetric ratio (70-94): (0-24); (5-8)]. These conditions rule out the use of pyrophoric catalysts and expensive platinum catalysts and allow conducting the process at normal pressure and room temperature. EFFECT: more efficient preparation process. 2 tbl
