Полученные соединени  хорошо раствор ютс  в этиловом эфире уксусной кислоты, ацетоне, этиловом спирте, но незначительно раствор ютс  в бензоле и практически не раствор ютс  в насыщенных углеводородах. Приведенные ниже примеры по сн ют способ получени  соответствующих изобретению соединений. Пример. Изопропиловый эфир 3-цианокарбаниловой кислоты. Смесь, состо щую из 11,8 г (0,1 моль) 3-аминобензонитрила,140 мл этилового эфира уксусной кислоты, 90 МП воды и 2,5 г (0,063 моль) окиси магни  ,при перемешивании смешивают по капл м с 13,5 г (0,11 моль) изопропилового эфира хлормуравьиной кислоты. Реакционную массу выдерживают в течение 3,ч при комнатной температуре, затем водную фазу подкисл ют .разбавленной сол ной кислотой и органический раствор промывают водой до нейтральной реакции промывных вод. Этилацетатную фазу отдел ют сушат над сернокислым магнием, фильт руют, после чего раствор упаривают досуха на роторном испарителе. Полученный неочищенный продукт перекристаллизовьшают из смеси этилового эфи ра уксусной кислоты и гексана.

Реакционный раствор нагревает до температуры примерно . С целью завершени  реакции реакционную массу выдерживают в течение 5 ч при комнатной температуре. Затем производ т отгонку растворител  на роторном испарителе и полученный остаток перекристаллизовывают из смеси метилового спирта и воды. Выход 9,3 г (81% от теории) ; т.пл. 101-102с. Аналогично получены и другие соединени , представленные в таблице .The present invention relates to a process for the preparation of new esters of carbanilic acid having herbicidal activity. It is known to obtain, for example, from 3-chlorocarbanilic acid propyl ester, which consists in the fact that halobenzoamine is reacted with the corresponding chloroformic ester 1. The application of the known reaction allows obtaining new compounds,. which in comparison with the known have better selectivity and higher activity. The goal is to achieve the preparation of esters of vannilic acid of the general formula Yu1-Co-oa where R is alkyl-Cj-Cg, cycloalkyl-C-C alkenyl-C, ,, alkynyl-C, -C, X - methyl-, methoxy group or chlorine atom; A p or 1, characterized in that the 3-aminobenzonitriles of the general formula TNg, where X and n have the above values, are reacted with chloroformic esters of the general formula SI-CO-OR, where R has the above values, in an organic or aqueous organic solvent in the presence of a hydrogen chloride acceptor at 20-40 ° C. The compounds obtained are well soluble in ethyl acetate, acetone, ethyl alcohol, but slightly soluble in benzene and practically not soluble in saturated hydrocarbons. The examples below explain the process for the preparation of the compounds according to the invention. Example. Isopropyl ester of 3-cyanocarbanilic acid. A mixture of 11.8 g (0.1 mol) of 3-aminobenzonitrile, 140 ml of ethyl acetate, 90 MP of water, and 2.5 g (0.063 mol) of magnesium oxide is mixed with stirring, 13, 5 g (0.11 mol) of isopropyl chloroformate The reaction mass is kept for 3 hours at room temperature, then the aqueous phase is acidified with diluted hydrochloric acid and the organic solution is washed with water until neutral wash water. The ethyl acetate phase is dried over magnesium sulfate, filtered, and the solution is evaporated to dryness on a rotary evaporator. The crude product obtained is recrystallized from a mixture of ethyl acetic acid ester and hexane. Yield 15.3 g (75% of theoretically calculated value); m.p. 94-96 ° C Cyclopentyl ester of 3-cyanocarbanilic acid. To a mixture of 4.3 g (0.05 mol) of cyclopentyl alcohol and 0.1 ml of triethylamine in 50 ml of diethyl ether, a solution of 7.2 g (0.05 mol) of 3-cyanophenyl isocyanate in 50 ml of diethyl alcohol is added dropwise with stirring. the ether. The reaction solution heats to a temperature of about. In order to complete the reaction, the reaction mass is kept for 5 hours at room temperature. The solvent is then distilled off on a rotary evaporator and the resulting residue is recrystallized from a mixture of methyl alcohol and water. Yield 9.3 g (81% of theory); m.p. 101-102s. Other compounds shown in the table are similarly prepared.
