Reaction Steps
To a solution of 2,6-dichloro-4-hydroxybenzaldehyde (225 mg, 1.18 mmol) in DMF (2.0 mL) was added potassium carbonate (0.81 g, 5.9 mmol) and methyl iodide (1.47 mL, 23.6 mmol). The resulting mixture was heated at 80° C. for 3 h. Reaction was diluted with water and ethyl acetate. The organic layer was separated and dried over Na2SO4, filtered and concentrated. The residue was purified by flash chromatography (20% ethyl acetate/hex) to give the desired product as a white solid (210 mg, 87%). LCMS for C8H7Cl2O2(M+H)+: m/z=205.
