Methanol → Methyl 6-fluoro-3-iodo-2-methylbenzoate

Participants

Reaction Steps

Trimethylsilyldiazomethane solution (2 M in Hexane) (18 mL, 35 mmol) was added dropwise to a stirred solution of the product of Step A (7.3 g, 33.2 mmol) in benzene containing 20% of methanol (total: 100 mL) at room temperature 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 200 mL of hexane containing 10% ethyl acetate. The filtrate was then concentrated to dryness to give the title compound as a bright yellow oil.
