Description
среды. Из растворителей чаще всего примен ют бензол, толуол, ксилол, хлорбензол, дихлорбензол , нитробензол.environment. Of the solvents, benzene, toluene, xylene, chlorobenzene, dichlorobenzene, nitrobenzene are most often used.
Исходные производные карбаминовой кислоты получают известными способами.The starting carbamic acid derivatives are prepared by known methods.
Иример. Производные карбаминовой кислоты (0,1 моль) добавл ют к пиридину (1 г), нагревают 3 час при 100-160°С и перемешивании . Продукт перекристаллизовывают из этанола и получают производные М-(3,5-дигалоидфенил )-о«сазолидина, перечисленные в таблице.Irimer. Carbamic acid derivatives (0.1 mol) are added to pyridine (1 g), heated for 3 hours at 100-160 ° C and with stirring. The product is recrystallized from ethanol to obtain the derivatives of M- (3,5-dihalo-phenyl) -o "sazolidine, listed in the table.
