Adding a certain compound to certain chemical reactions, such as: 83647-43-2, (3-Bromo-2-methylphenyl)methanol, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Product Details of 83647-43-2, blongs to alcohols-buliding-blocks compound. Product Details of 83647-43-2
To a solution of 20.00 g (99.47 mmol, 1.0 eq) of (3-bromo-2-methyl-phenyl)methanol 1A and 24.26 g (198.94 mmol, 2.0 eq) of phenylboronic acid in 156 mL of toluene and 52mL of EtOH, were added 812.3 mg (0.995 mmol, 0.01 eq) of Pd(dppf)Cl2.CH2Cl2 and 25.07g (2 M, 149.21 mL, 3.0 eq) of NaHCC under nitrogen gas. The mixture was stirred at 80C for 12 hours. The mixture was separated, and the aqueous phase was extracted with 2 x 400 mL of ethyl acetate (EtOAc). The combined organic phase was washed with 2 x 200 mL of brine, dried over Na2SC>4, filtered and the solvent was concentrated. The residue was purified by column eluted with petroleum ether/ethyl acetate = 25/1-10/1 to give crude product (25 g) as a yellow solid. The solid was smashed in 100 mL of petroleum ether, and the suspension was filtered to give 15.00 g (74.62%) of (2-methyl-[l,l’-biphenyl]-3-yl)methanol as a white solid. lH NMR (400 MHz, CDC13): delta 7.40-7.31 (m, 4H) 7.25-7.22 (m, 3H) 4.75-4.74 (m, 2H) 2.21 (m, 3H) 1.62~1.59(m, 1H).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,83647-43-2, (3-Bromo-2-methylphenyl)methanol, and friends who are interested can also refer to it.
