Related Products of 60789-54-0, These common heterocyclic compound, 60789-54-0, name is ((4-Bromobutoxy)methyl)benzene, 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.
Reference Example 18 4-Benzyloxy-3-(4-benzyloxybutoxy)benzonitrile 4-Benzyloxy-3-hydroxybenzonitrile (3.4g) and potassium carbonate (6.3g) were dissolved in N,N-dimethylformamide (20mL). To the mixture was added benzyl 4-bromobutylether (3mL), and the mixture was stirred at 50C for 16 hours. To the reaction mixture was added dropwise 2mol/L hydrochloric acid (4mL), and the resulting mixture was extracted with ethyl acetate. The organic layer was washed with brine and dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure, and the obtained residue was purified by column chromatography on silica gel (eluent:ethyl acetate/hexane=1/5) to give the title compound (5.9g). 1H-NMR (CDCl3) delta ppm: 1.70-2.10 (4H, m), 3.55 (2H, t, J=6.1Hz), 4.04 (2H, t, J=6.5Hz), 4.49 (2H, s), 5.17 (2H, s), 6.90 (1H, d, J=8,2Hz), 7.08 (1H, d, J=1.9Hz), 7.19 (1H, dd, J=1.9Hz, 8.2Hz), 7.24-7.45 (10H, m)
Statistics shows that ((4-Bromobutoxy)methyl)benzene is playing an increasingly important role. we look forward to future research findings about 60789-54-0.
