Reaction Steps
3-[7-Chloro-5-fluoro-2(3H)benzoxazolinon-4-yl]-1-methyl-6-trifluoromethyl-2,4(1H,3H)-pyrimidinedione (0.50 g) was dissolved in anhydrous toluene (15 ml) and methyl pyruvate (0.15 g) was added. The solution was refluxed with azeotropic removal of water for 2 hours and the solvent was then removed under reduced pressure. The residue was chromatographed on silica gel using hexane-ethyl acetate (3:1) as the eluent to afford the title compound (0.23 g).
