Beschreibung
Zusammenfassung:	FIELD: organic chemistry, chemical technology. SUBSTANCE: aminobenzoic acid esters were synthesized by reduction of the corresponding nitrobenzoic acid esters and the end product is isolated from reaction mixture using solvents. To obtain the additional yield of the end product from mother liquor the repeated reduction is occurred. Synthesized compounds were used in chemical-pharmaceutical industry. EFFECT: simplified extraction of the end product, high quality. Способ получения сложных эфиров аминобензойной кислоты путем восстановления соответствующих сложных эфиров нитробензойной кислоты выделением целевого продукта из реакционной смеси с помощью растворителей и дополнительным выделением целевого продукта из маточника, отличающийся тем, что маточник подвергают повторному восстановлению.
