(54) СПОСОБ ПОЛУЧЕНИЯ ДИУРЕТАНОВ(54) METHOD FOR OBTAINING DIURETHANES

s присутствии акцептора кислоты, предпочтительно в смеси уксусиого эфира и воды в присутствии углекислого кали .s in the presence of an acid acceptor, preferably in a mixture of ethyl acetate and water in the presence of potassium carbonate.

Приме р, 3- (Метоксикгв бониЛeiMHHo ) -фениловый эфир N-|2-хлорэтил) -карбаминсвой кислоты.Example 3- (methoxygv bony LeiMHHo) -phenyl ester of N- | 2-chloroethyl) -carbamine acid.

В раствор 23 г гидрохлорида N-J2r -хлорэтил)-анилина в ЗОмлводы и 50мл этилацетата при перемешивании и 1015°С прибавл ют по капл м раствор 22,9г 3-метоксик арбониламинофенилового эфира хлормуравьиной кислоты в 50 мл этилацётата и одновременно раствор 30,5 г углекислого кали To a solution of 23 g of N-J2r-chloroethyl) -aniline hydrochloride in 30 ml of ethyl acetate and 50 ml of ethyl acetate under stirring and 1015 ° C, a solution of 22.9 g of 3-methoxy-arbonylaminophenyl chloroformate in 50 ml of ethyl acetate and at the same time a solution of 30.5 g g potassium carbonate

в 150 мл воды. Перемешивают при 15 С в течение 30 мин, отдел ют органическую фазу, разбавл ют ее 100 мл этилацетата при последовательно промывают разбавленным едким натром, е ВОДОЙ, разбавленной сол ной кислотой и водой, сушат сернокислым магнием и упаривают при пониженном давлении, По;гученный 1маслообразньпЯ; продукт, вскоре закристаллизовываетс , его перекристаллизовывают из смеси этилацетат-пентан ,.in 150 ml of water. The mixture is stirred at 15 ° C for 30 minutes, the organic phase is separated, diluted with 100 ml of ethyl acetate and washed successively with dilute sodium hydroxide, WATER, dilute hydrochloric acid and water, dried with magnesium sulfate and evaporated under reduced pressure; ; the product soon crystallized, recrystallized from ethyl acetate-pentane,.

Выход 30 г (8б%),Т.пл,98-100 С, Аналогичным способом получают соединени , указанные в таблице.Yield 30 g (8b%), Tp, 98-100 ° C. The compounds listed in the table are prepared in a similar way.
