A FACILE CONVERSION OF 5-TRIFLUOROMETHYL-5,6-DIHYDROURACILS TO 5-TRIFLUOROMETHYLURACILS
5-Trifliuoromethyl-5,6-dihydrouracils were directly converted to the corresponding 5-trifluoromethyluracils by the reaction with copper(II) bromide in dimethylformamide/water or dimethylformamide/acetic acid in good to excellent yields.
