Reaction Steps
N-Boc-L-tyrosine benzyl ester (0.371 g, 1 mmol) was dissolved in acetone (5 mL) and cesium carbonate (0.650 g, 2 mmol) was added followed by chloroacetonitrile (0.150 g, 2 mmol). The mixture was then reflux for 2 h. The reaction was cooled to room temperature and insoluble salts removed by filtration using acetone for washings. Volatiles were removed under reduced pressure and the residue dissolved in DCM. The solution was washed with brine, dried (MgSO4) and concentrated to give the desired product as an oil (450 mg).
