Reaction Steps
To a stirred solution of methyl 5-chloro-3-(cyclopentylamino)-2-methylbenzoate (0.62 g, 2.32 mmol) in dry DMF (10 mL), cesium carbonate (3.78 g, 11.6 mmol) and ethyl iodide (5.43 g, 34.8 mmol) were added and the resulting reaction mass was heated at 80° C. for 18 h. On completion, reaction mixture was cooled to room temperature and filtered. The residue was washed with ethyl acetate and filtrate concentrated and purified by column chromatography to afford desired methyl 5-chloro-3-(cyclopentyl(ethyl)amino)-2-methylbenzoate (0.101 g, 15%).
