Methanol → Methyl 3-bromo-2,4,5-trifluorobenzoate

Participants

Reaction Steps

772 g of 3-bromo-2,4,5-trifluoro-benzoyl fluoride are added dropwise to 1460 ml of methanol and 340 g of triethylamin, while cooling with ice. The mixture is stirred at room temperature for 1 hour. The reaction mixture is concentrated in vacuo and the resulting residue is taken up in water and methylene chloride. The water is extracted with methylene chloride once more. The organic phase is dried with Na2CO3 and concentrated in vacuo. The resulting residue is distilled in vacuo.
