To a suspension of 4-(4-methoxypyridin-2-yl)fluorobenzene (0.71 g) in sulfuric acid (10 ml) was added fuming nitric acid (0.176 ml) dropwise at 0° C., and the mixture was stirred at 0° C. for 30 minutes. The reaction mixture was poured into an aqueous sodium hydroxide solution (4N) and extracted with ethyl acetate. The separated organic layer was washed with water and brine, dried over sodium sulfate and evaporated under reduced pressure to give 2-fluoro-5-(4-methoxypyridin-2-yl)nitrobenzene (831 mg).
