Acetic Acid → Methyl 5-bromo-2-hydroxy-4-methoxybenzoate

Participants

Reaction Steps

To a solution of 5-bromo-2-hydroxy-4-methoxybenzoic acid (2.00 g) in methanol (10.0 mL) was added 0.6M (diazomethyl)trimethylsilane/hexane solution (14.8 mL) under ice-cooling, and the mixture was stirred for 3 hr. To the reaction mixture was added acetic acid (0.12 mL), and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (2.08 g).
