Methanol → Methyl 3-Bromo-2-methylbenzoate

Participants

Reaction Steps

Trimethylsilyldiazomethane solution (2M in Hexane) (60.5 mL, 121 mmol) was added dropwise to a stirred solution of 3-bromo-2-methylbenzoic acid (26 g, 121 mmol) in benzene containing 20% of methanol (total: 300 mL) at rt until solution retained a yellow color. The mixture was concentrated to remove the organic solvent. The remaining oil was poured over a silica gel plug in a 60-mL filter frit funnel and eluting with 500 mL of hexane containing 10% ethyl acetate. The filtrate was then concentrated to dryness to afford the title compound as a bright yellow oil.
