Reaction Steps

3-(4-Chloro-6-fluoro-3-methoxy-2-nitrophenyl)-1-methyl-6-trifluoromethyl-2,4(1H, 3H)-pyrimidinedione (7.5 g, 18.9 mmol) was dissolved in acetic acid (75 ml) and 4.2 g (75.6 mmol) of iron powder was added. The solution was stirred at ambient temperature under nitrogen atmosphere for 6 hr and water was added. Extraction was carried out with ethyl acetate. Organic layer was washed with water, brine, and dried with anhydrous sodium sulfate followed by evaporation to afford the title compound (6.8 g).
