Methanol → Methyl 3-bromo-4-fluorobenzoate

참여 물질

반응 단계

221 g (1 mole) of 4-fluoro-3-bromobenzoyl fluoride were added dropwise to a mixture of 96 g (3 moles) of methanol and 1 g of pyridine. The reaction mixture was then boiled for a further 2 hours under reflux and was subsequently worked up by distillation. 217 g (93% of theory) of 4-fluoro-3-bromobenzoic acid methyl ester were thus obtained in the form of a colorless oil which solidified when cold and had a boiling point of 124° C./22 mm Hg (melting point 29° to 30° C.).
