Х( - метокси или этоксикарбониламиногруппа, низший алкил, низший алкоксид;X ( - methoxy or ethoxycarbonylamino group, lower alkyl, lower alkoxide;
X - Н, низший алкил, хлор или Х^ и X 2 образуют фурановое кольцо, которое может быть. замещено двумя метильными заместителями, или бензольное кольцо,X - H, lower alkyl, chlorine or X ^ and X 2 form a furan ring, which may be. substituted by two methyl substituents, or a benzene ring,
Соединения общей формулы (1) используются в качестве компонентов гербицидных композиций.Compounds of general formula (1) are used as components of herbicidal compositions.
Целью изобретения является упрощение технологии.The aim of the invention is to simplify the technology.
Пример 1. 4,3 г (0,025 моль) метил-(3-оксифенил)карбамата в 15 мл 5 ацетона вводят' во взаимодействие ·^ с 7,3 г (0,025 моль) сульфимида N-фенилкарбамоилбензойной кислоты в присутствии 2,56 г (θ,Ο25 моль) триэтиламина. Реакцию ведут· 15 мин при 40°C. Затем реакционную массу смешивают с 40 мл воды и охлаждают до 5~10 С, Через 30 мин продукт отфильтровывают, промывают и сушат.Example 1. 4.3 g (0.025 mol) of methyl- (3-hydroxyphenyl) carbamate in 15 ml of 5 acetone are reacted with 7.3 g (0.025 mol) of N-phenylcarbamoylbenzoic acid sulfimide in the presence of 2.56 g (θ, Ο25 mol) triethylamine. The reaction is carried out · 15 min at 40 ° C. Then the reaction mass is mixed with 40 ml of water and cooled to 5 ~ 10 C. After 30 minutes, the product is filtered off, washed and dried.
. Получают 5,5 г 3-метоксикарбонил15 аминофенил-фенилкарбамата с .т.пл.. Obtain 5.5 g of 3-methoxycarbonyl15 aminophenyl-phenylcarbamate with a melting point of.
150-152°(х - фенил, Х<- 3-метоксикарбониламино, Х?~ Н). Выход 77%.150-152 ° (x - phenyl, X <- 3-methoxycarbonylamino, X? ~ H). Yield 77%.
В примерах 2-12 процесс ведут аналогичным образом. Конкретные условия и результаты опытов приведены в таблице.In examples 2-12, the process is conducted in a similar manner. Specific conditions and experimental results are shown in the table.
