Description

щей формулы Г, отличительна  особенност которого состоит в том, что аналин общей формулы R -NH-R(и, где R. и R имеют вышеуказанные значени  подвергают взаимодействию с цикпопропил изотиоцианатом в среде органического растворител . Циклопропилизоцианат может быть получен фосгенизацией гидрохлорида циклопропиламина при повышенной температуре в инертном растворителе или путем пирсьлиза 1-.циклопропип-3,3-дифенилмочеви -. ны или ифугими известными способами. Подход щими средами  вл ютс  инертные по отношению к участвующим в реакции компонентам растворители. В качестве таковых следует назвать алифатические и ароматические углеводороды, как петролейный эфир, циклогексан, бензол, толуол и ксилол; галогенированные углеводороды , как метиленхлорид, хлороформ, четыреххлористый углерод, и галогенированные этилены , эфироподобные соединени , как диэтиловый эфир, диизопропило65 64 вый эфир, тетрагидрофуран и диоксан; кетоны, как ацетон, метипиэобутипкетон и изофорон; спожные эфиры, как ме иповый и этиповый эфир уксусной кис поты; амиды кислот, как диметилсульфамид. и амид гексаметилфосфорной кислоты; нитрилы карбоновых кислот, как ацетонитрил , и многие другие. Пример. 1-циклопррпил-3(4-фторфенил )-мочевина В раствор ИД г 4-фторанипина в ,00 мл диизопропилового эфира при перемешивании при комнатной температуре прикапывают 8,4 мл циклопропилизоцйаната . Осажденную по истечении некоторого времени 1-циклопропи7 -3-(4-фторфеНИЛ )-мочевину отсасывают, промывают диизопропиловым эфиром и сушат. Выход 18,8 г (96,8% от теории), т. пл. 205«С. . В таблице приведены соединений, которые аналогично могут быть получены, их выход и элементный состав, в скобках даны найденные значени .
