PROCESS FOR THE PREPARATION OF 4-METHYLURACIL |
| abstract |
4-Methyluracil can be prepared in a one-step process in good yields with short reaction times technically simply by reacting urea with a Acetessigsaeureester having 1 to 4 carbon atoms in the alcohol radical, in the presence of dimethylformamide, a catalyst and an entraining agent for water azeotropically and saponified the obtained b-Ureidocrotonsaeureester in a conventional manner. |
