Reaction Steps
To a solution of 4-acetyl-3-chlorobenzoic acid (synthesized by the method of Tetrahedron 1988, 44, 1631, 700 mg, 3.52 mmol) in N,N-dimethylformamide (4 mL) were added potassium carbonate (974 mg, 7.05 mmol) and iodomethane (658 μL, 10.57 mmol) at room temperature, and the mixture was stirred at room temperature for 1 hour. To the reaction solution was added water, and the mixture was extracted with ethyl acetate three times. The organic layer was combined, filtered through Phase-separator (Varian Inc.), and then concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=100:0→75:25) to give methyl 4-acetyl-3-chlorobenzoate (707 mg, 94%) as a pale yellow powder.
