To a suspension of 2-bromo-4-methoxypyridine (483 mg), 3-nitrophenylboronic acid (643 mg) and tetrakis(triphenylphosphine)-palladium (148 mg) in 1,2-dimethoxyethane (10 ml) was added 2M aqueous solution of sodium carbonate (2.78 ml). The mixture was stirred at 90° C. for 6 hours under a nitrogen atmosphere, then cooled to room temperature and diluted with dichloromethane. The organic layer was separated, washed with water and brine and dried over sodium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by column chromatography (silica gel 40 g, 50-100% dichloromethane in n-hexane) to give 3-(4-methoxypyridin-2-yl)-nitrobenzene (365 mg).
