Procedure
2-Chloro-3-amino-benzoic acid methyl ester (1.20 g, 6.47 mmol) was placed in a round bottomed flask with DMF (5 mL), Potassium carbonate (1.97 g, 14.2 mmol) and methyl iodide (0.89 mL, 14.22 mmol) were added. A reflux condenser was fitted and the reaction was heated to 60° C. for 12 h. The reaction was cooled to rt, diluted with water (20 mL) and extracted with ethyl acetate (3×20 mL). The organics were dried (MgSO4), concentrated, then purified by column chromatography using hexanes/ethyl acetate (1:1) to afford 2-chloro-3-dimethylamino-benzoic acid methyl ester (1.04 g, 75%)
