Method for producing bisoxazolidine containing urethane group |
| abstract |
(57) [Summary] [Object] To provide a production method for producing a bisoxazolidine containing a urethane group in a high yield by a simple operation without using a harmful isocyanate. [Structure] General formula (I): A method for producing bisoxazolidine corresponding to R-hydroxyethyloxazolidine II from the reaction medium in the presence of a transesterification catalyst according to the following reaction scheme: Process for the preparation of the above bisoxazolidines, characterized by reacting the diamine with the dicarbamate (III) under conditions of temperature and pressure which allow the removal of the 5 OH alcohols by distillation as they are produced.
