Use | 2-methyl-5-bromobenzoic acid is a pharmaceutical intermediate, it has been reported in the literature that it can be used to prepare canagliflozin. |
preparation | with 2-methylbenzoic acid as the starting material, under the action of metal reagent Fe powder and superstrong acid catalyst triflic acid, the intermediate 2-methyl-5-bromobenzoic acid was synthesized by adding liquid bromine with a molar ratio of 1.05, and the solvent liquid bromine was pretreated with absolute anhydrous molecular sieve. The yield was above 85%. |
