Method for producing cyclic urea derivative |
| abstract |
(57) [Problem] A method for producing a cyclic urea derivative. SOLUTION: Formula I: embedded image A cyclic urea derivative represented by the following formula: Is converted to a urea derivative of the formula III: And b) hydrogenating the reaction product from step a) in the presence of a metal-containing catalyst. The cyclic urea derivative can be produced in a high yield, and the hydrogenation can be carried out continuously, so that the economic efficiency can be remarkably improved. |
