Paragraph 0034-0035; 0037-0038; 0041-0042, (2021/07/17)
The invention relates to the technical field of organic synthesis, in particular to a method for synthesizing 2,6-diethyl-4-methylphenylacetate by taking 2,6-diethyl-4-methylbromobenzene as a raw material, which comprises the following steps: firstly reacting 2,6-diethyl-4-methylbromobenzene with n-butyllithium and then conducting reacting with borane trimethyl ester to generate 2,6-diethyl-4-methylphenylboronic acid; and reacting the 2,6-diethyl-4-methylphenylboronic acid with glycine alkyl ester hydrochloride to generate the 2,6-diethyl-4-methylphenylacetate. The preparation method of the 2,6-diethyl-4-methyl phenylacetate provided by the invention has the advantages that the steps are fewer, the use of an expensive noble metal catalyst and a highly toxic cyaniding reagent is avoided, the cost is reduced, the process is simplified, the yield is higher, the defects in the prior art are overcome, and the preparation method is suitable for large-scale industrial production.
