Abstract
A process for the preparation of 2-oxo-4-trifluoromethyl-1,2-dihydropyrimidine-5-carboxylic esters is characterized in that β-aminocrotonates (cinnamates) are subjected to reaction with benzene N-(1-chloro-2,2,2-trifluoroethylidene)carbamate in the presence of organic base in aprotic solvent at room temperature followed by separation of desired products by conventional methods.
