FIELD: organic chemistry and chemical technology. SUBSTANCE: invention relates to the novel method of synthesis of amlodipine bezylate of the formula (I) 
showing the expressed antihypertensive and anti-anginal properties. Method of synthesis involves hydrolysis of compound of the formula (II) 
with benzenesulfoacid of the formula (III) 
in the mixture of water and organic solvent that can be mixed or nonmixed with water, for example, n-butanol, ethyl acetate, monohydric alcohol with 1-3 carbon atoms. The parent compound (II) is synthesized by interaction of compound of the formula (IX) 
with hexamethylenetetramine of the formula (X) 
. EFFECT: simplified method, high yield of reaction products without isolation of amplodipine base. 6 cl, 1 dwg, 8 ex
