Participants

Reaction Conditions

Reaction Steps

To a stirred solution of methyl 3-bromo-5-(cyclopentylamino)benzoate (0.3 g, 0.96 mmol) in DMF (5 mL), cesium carbonate (0.628 g, 1.92 mmol) and ethyl iodide (0.748 g, 4.8 mmol) were added; resulting reaction mass was heated at 80° C. for 24 h. On completion, reaction mass was cooled to room temperature and filtered, residue was washed with ethyl acetate and filtrate was concentrated and then purified by column chromatography to afford desired compound (0.150 g, 46%).
