General procedure for the synthesis of 2,3-difluoro-6-methoxybenzoic acid from 2,3-difluoro-6-methoxybenzaldehyde: 1. Preparation of reaction system: 2,3-difluoro-6-methoxybenzaldehyde (0.5 g, 2.91 mmol) was suspended in potassium hydroxide solution (3 g KOH dissolved in 20 ml of water). 2. Oxidizing reaction: hydrogen peroxide solution (27.5% w/w, 4 ml) was added to the above suspension, followed by heating the reaction at 70°C for 2 hours. 3. Acidification: after completion of the reaction, the reaction mixture was acidified to pH 2 with concentrated hydrochloric acid. 4. Extractive separation: the acidified reaction mixture was washed with ethyl acetate. 5. Drying and concentration: the organic phases were combined, dried with anhydrous magnesium sulfate, filtered and the solvent was evaporated in vacuum. 6. Purification: Further purification by azeotropy with toluene afforded 2,3-difluoro-6-methoxybenzoic acid as a white solid (500 mg, 91% yield). Remarks: LC/MS analysis showed a retention time of 12.08 min and no molecular ion peak was observed.
