Triacetoxyperiodinane → Methyl 3-bromo-2-methyl-6-(2-oxoethoxy)benzoate

Participants

Reaction Steps

To a solution of methyl 3-bromo-6-(2-hydroxyethoxy)-2-methylbenzoate (126a, 126 mg, 0.436 mmol) in DCM (5 mL) was added Dess-Martin periodinane (192 mg, 0.429 mmol). The solution was stirred at room temperature for 2 hours. The solution was purified directly by column chromatography (silica gel, heptanes/EtOAc) to give methyl 3-bromo-2-methyl-6-(2-oxoethoxy)benzoate (126b, 111 mg, 90% yield) as a clear oil.
