Methyl iodide → Methyl 4-bromo-2-methylbenzoate

Participants

Reaction Steps

To a solution of 4-bromo-2-methylbenzoic acid (5.0 g, 23.2 mmol) in DMF (50 mL) was added potassium carbonate (6.4 g, 46.4 mmol) and iodomethane (6.6 g, 46.479 mmol). The mixture was stirred at RT for 12 h then diluted with water and extracted with ethyl acetate. The combined organic layer was washed with brine, dried over Na2SO4 and concentrated in vacuo. Purification by normal phase silica gel column provided methyl 4-bromo-2-methylbenzoate as a colorless oil.
