Versuchsvorschrift

To a solution of commercial N-Fmoc-L-serine (1.5 g, 4.58 mmol) in EtOAc (40 ml), a solution of t-butyl 2,2,2-trichloroacetimidate (4.00 g, 18.32 mmol) in cyclohexane (18 ml) was added dropwise. After stirring at room temperature for 24 hrs, the solution was evaporated and the residue was purified by flash chromatography (n-Hexane/EtOAc 70:3), yielding the title compound (1.20 g, 68%).
