The downstream synthesis method of this compound is introduced below.
Preparation 55 To a suspension of 2-bromo-4-methoxypyridine (1.21 g), 4-chlorophenylboronic acid (1.21 g) and tetrakis(triphenylphosphine)-palladium (372 mg) in 1,2-dimethoxyethane (20 ml) was added 2M aqueous solution of sodium carbonate (7.74 ml). The mixture was stirred at 80 C. for 12 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. 2-Propanol was added to the residue. The precipitate was collected by filtration and dried under reduced pressure to give 4-(4-methoxypyridin-2-yl)-chlorobenzene (1.03 g). 1H-NMR (CDCl3): delta3.91(3H,s), 6.78(1H,dd,J=5.7 Hz,2.4 Hz), 7.19(1H,d,J=2.4 Hz), 7.42(2H,d,J=8.6 Hz), 7.90(2H,d,J=8.0 Hz), 8.51(1H,d,J=5.7 Hz)
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 89488-29-9, 2-Bromo-4-methoxypyridine.
