Procedure
To a solution of (2E)-N-[4-(2-{[(tert-butyl)amino]sulfonyl}phenyl)phenyl]-3-(3-cyanophenyl)-2-fluorobut-2-enamide (230 mg, 0.47 mmol) in 15 ml DMF was added cesium carbonate (460 mg, 1.41 mmol) and bromomethyl acetate (355 mg, 2.35 mmol). The reaction mixture was stirred at room temperature for 4 hours then diluted with 25 ml of ethyl acetate. Organic was washed with 3×25 ml water, 3×25 ml saturated brine solution, dried over magnesium sulfate, filtered and concentrated in vacuo to give methyl 2-{(2E)-N-[4-(2-{[(tert-butyl)amino]-sulfonyl}phenyl)phenyl]-3-(3-cyanophenyl)-2-fluorobut-2-enoylamino}acetate (230 mg, 86%) as yellow foam. ES-MS (M+H+): 563.2.
