Description
2-Methyl-3-biphenylmethanol is a pharmaceutical intermediate and organic chemical synthesis reagent, which can be used in the preparation of drugs such as Bifenthrin and PD-L1 inhibitors, and also in the synthesis of other organic compounds such as 2-methyl-3-phenylphenethylboronic acid pinacol ester, biphenyl-1,2,3-triazole couplings and biphenyl alcohols.
Synthesis
Carrying out a Suzuki coupling reaction between 3-bromo-2-methylbenzoic acid and phenyl substituted boric acid or phenyl substituted borate to obtain 3-phenyl-2-methylbenzoic acid, and then carrying out a reduction reaction to obtain 2-Methyl-3-biphenylmethanol, wherein the Suzuki coupling reaction is carried out at 10-150 DEG C for 1-12 hours under the action of an alkali. 3-phenyl-2-methylbenzoic acid can be directly reduced with a reducing agent such as borane and lithium aluminium hydride to obtain 2-Methyl-3-biphenylmethanol.
