Related Products of 60633-25-2, These common heterocyclic compound, 60633-25-2, name is 2-Bromo-4-chloro-1-methoxybenzene, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Palladium acetate(21mg, 7mol%) was added to a solution of 2-bromo-4-chloroanisole(300mg, 1.4mmol), styrene(211mg, 2mmol), triethylamine(13 muL, 0.1mmol) and triphenylphosphine(50mg, 1.9mmol) in acetonitrile(6mL), and the mixture was refluxed for 8 hours under argon atmosphere. After the reaction mixture was cooled to room temperature, the solvent was concentrated under reduced pressure and the obtained residue was diluted with ethyl acetate(15mL). After the solution was washed successively with 2N hydrochloric acid, water and brine, dried over anhydrous sodium sulfate, the residue obtained by evaporation of the solvent under reduced pressure was purified by column chromatography on silica gel(n-hexane:ethyl acetate=10:1) to give the title compound(118mg, 35.6%) as a white powder.1H-NMR(CDCl3):d 3.85(3H, s), 6.80(1H, d, J=8.8Hz), 7.08(1H, d, J=16.8Hz), 7.17(1H, dd, J=8.8, 2.5Hz), 7.20-7.42(4H, m), 7.51-7.55(3H, m).
The synthetic route of 60633-25-2 has been constantly updated, and we look forward to future research findings.
