Synthetic Route of 90562-10-0, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 90562-10-0, name is 1-Bromo-4-(3-bromopropyl)benzene belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
(41-4) Synthesis of [5-(2-{4-[3-(4-bromophenyl)propoxy]-3-trifluoromethylphenyl}ethyl)-2,2-dimethyl-1,3-dioxan-5-yl]carbamic acid t-butyl ester (compound 41-4) Reference Example compound 2-6 (500 mg) was dissolved in N,N-dimethylformamide (10 ml), potassium carbonate (494 mg) and compound 41-3 (447 mg) were added, and the mixture was stirred at 80C for 1.5 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate, washed with water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to give the object product (820 mg) as a white solid. 1H-NMR(CDCl3) 5 (ppm): 1.43(3H, s), 1.44(3H, s), 1.47(9H, s), 1.93-1.98(2H, m), 2.06-2.10(2H, m), 2.51-2.56(2H, m), 2.77-2.81(2H, m), 3.69(2H, d, J=11.7Hz), 3.89(2H, d, J=11.7Hz), 3.96(2H, t, J=6.0Hz), 5.00(1H, brs), 6.83(1H, d, J=8.5Hz), 7.05-7.09(2H, m), 7.24-7.27(1H, m), 7.36-7.43(3H, m).
The synthetic route of 1-Bromo-4-(3-bromopropyl)benzene has been constantly updated, and we look forward to future research findings.
