Versuchsvorschrift

To a suspension of NaH (60%, 2.0 g, 51 mmol) in dry DMF (125 ml) cooled at 0° C., a solution of 2-(3-butoxyphenyl)-(tert-butoxycarbonyl)ethylamine (7.5 g, 25.5 mmol) in dry DMF (125 ml) was added dropwise. After 1 h at room temperature, 2-chloro-N,N-dimethylacetamide (5.2 ml, 51 mmol) was added and the mixture was stirred for 16 h at room temperature. H2O (10 ml) was added and the solvent was evaporated under reduced pressure. The residue was dissolved in H2O (150 ml) and extracted with CH2Cl2 (2×150 ml). The collected organic phases were dried over Na2SO4, filtered and evaporated. The crude was purified by flash chromatography (petroleum ether/EtOAc 4:6) affording the title compound (7.2 g, 75%) as light yellow oil.
