Versuchsvorschrift

To a solution of (R)-tert-Butyl-4-chloro-2-{(thiomorpholine-3-carboxamido)-methyl}-benzyl-carbamate (0.56 g, 1.40 mmol) in CH2Cl2 (25 mL) was added triethyl amine (0.59 mL, 4.2 mmol) and solution of (2R)-1-chloro-3,3-dimethyl-1-oxobutan-2-yl acetate (0.496 g, 2.8 mmol) in CH2Cl2 (5 mL) dropwise at −10° C. and the resulting mixture was allowed to warm up to room temperature over 1 h. The reaction mixture was quenched with water (50 mL) and extracted with EtOAc (3×25 mL). The combined organic layers were washed with brine solution, dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure. The residue was purified by reverse phase combiflash column chromatography (C18; eluent: 10-100% acetonitrile/water) to obtain the title compound (0.42 g) as a white solid.
