| titleOfInvention | Method for producing methylurea compound |
| abstract | The present invention relates to formula (2) without using methyl isocyanate, which is problematic in terms of availability and safety. A process for producing a methylurea compound represented by the formula (1) with high selectivity. (A) Formula (1) (In the formula, Ar represents an aromatic group which may be substituted with a substituent other than an amino group, and n represents an integer of 1 to 3). A step of reacting an N-methylcarbamic acid compound represented by the formula (2) with an excess amount of ethylenediamine to obtain a reaction solution containing the methylurea compound represented by the formula (2) and unreacted ethylenediamine, (B) a step of concentrating the reaction solution to remove ethylenediamine in the reaction solution and taking out a methylurea compound represented by the formula (2); A process for producing a methylurea compound, comprising: [Selection figure] None |
