3-(4-Chloro-6-fluoro-3-methyl-2-nitrophenyl)-6-trifluoromethyl-2,4(1H, 3H)-pyrimidinedione (10.1 g) was dissolved in dimethylformamide (100 ml) and potassium carbonate (5.7 g, 41.3 mmol) and dimethylsulfate (11.9 g, 55.1 mmol) were added. Solution was stirred at ambient temperature for 14 hr, water was added and product extracted with ethyl acetate. The title compound was separated by column chromatography on silica gel (eluent, hexane-ethyl aceatate, 9:1; 8.5 g).
