Procedure

To a stirred solution of mixture of cis isomer of methyl 5-bromo-3-((4-((tert-butoxycarbonyl)amino)cyclohexyl)amino)-2-methylbenzoate (4 g, 9.09 mmol) in acetonitrile (50 mL) was added cesium carbonate (5.9 g, 18.18 mmol) and methyl iodide (6.45 g, 45.45 mmol). The resulting reaction mixture was heated at 80° C. for 7 h. On completion, the reaction mixture was cooled to room temperature and filtered, the residue was washed with ethyl acetate and filtrate was concentrated to afford desired crude compound which then purified by column chromatography giving desired compound (1.4 g, 34%).
