Manchand, Percy S. published the artcileA convenient synthesis of 3,5-dimethoxy-4-methylbenzoic acid, Product Details of C9H8Br2O2, the main research area is benzoic acid dimethoxymethyl; bromination toluic acid; methoxylation methyldibromobenzoate.
4-MeC6H4CO2Me, prepared in 95% yield from 4-MeC6H4CO2H, was stirred with AlCl3 and Br at room temperature 30 min and then at 80-8° 1 h to give 65% 3,5,4-Br2MeC6H2CO2Me (I). Treating I in pyridine with NaOMe in the presence of CuCl gave 81% 3,5,4-(MeO)2MeC6H2CO2Me, which was hydrolyzed to the title acid.
Synthesis published new progress about Methoxylation. 74896-66-5 belongs to class bromides-buliding-blocks, name is Methyl 3,5-dibromo-4-methylbenzoate, and the molecular formula is C9H8Br2O2, Product Details of C9H8Br2O2.
