Versuchsvorschrift

To a solution of 2-bromo-6-methylbenzoic acid (5.02 g) and methyl iodide (2.9 mL) in N,N′-dimethylformamide (30 mL) was added powdered potassium hydrogen carbonate (4.67 g). The mixture was stirred at ambient temperature for 16 hours and concentrated. The concentrate was partitioned between ethyl acetate and water. The extract was washed with brine and concentrated, and the concentrate was purified by flash chromatography on silica gel with 60% ethyl acetate in hexanes.
