With sodium carbonate; In methanol; 1,2-dimethoxyethane; | Preparation 72 To a suspension of 2-bromo-4-methoxypyridine (2.5 g), 4-methyl-3-nitrophenylboronic acid (3.37 g) and tetrakis(triphenylphosphine)-palladium (768 mg) in 1,2-dimethoxyethane (100 ml) was added 2M aqueous solution of sodium carbonate (18.6 ml). The mixture was stirred at 80 C. for 7 hours under a nitrogen atmosphere, then cooled to room temperature and diluted with ethyl acetate. The organic layer was separated, washed with water and brine and dried over sodium sulfate. The solvent was evaporated under reduced pressure. Methanol was added to the residue. The precipitate was collected by filtration and dried under reduced pressure to give 4-(4-methoxypyridin-2-yl)-2-nitrotoluene (3.09 g). 1H-NMR (CDCl3): δ2.65(3H,s), 3.93(3H,s), 6.82(1H,dd,J=5.7 Hz,2.4 Hz), 7.25(1H,d,J=2.7 Hz), 7.43(1H,d,J=8.0 Hz), 8.14(1H,dd,J=8.0 Hz,2.0 Hz), 8.53(1H,d,J=5.8 Hz), 8.58(1H,d,J=2.0 Hz) |
