Reaction Conditions

Reaction Steps

To a suspension of 4-(4-methoxypyridin-2-yl)chlorobenzene (500 mg) in sulfuric acid (4 ml) was added fuming nitric acid (0.2 ml) dropwise at 0° C., and the mixture was stirred at 5° C. for 30 minutes. The reaction mixture was poured into a saturated aqueous sodium hydrogencarbonate solution and extracted with ethyl acetate. The separated organic layer was washed with water and brine, dried over sodium sulfate and evaporated under reduced pressure. The residue was triturated with diisopropyl ether, filtered, washed with diisopropyl ether and dried under reduced pressure to give 1-chloro-4-(4-methoxypyridin-2-yl)-2-nitrobenzene (601 mg).
