Versuchsvorschrift

To {benzyl[(1R)-2-oxocyclohexyl]amino}acetonitrile (298 mg, 1.230 mmol) in THF (9 ml) at −78° C. was added ethylvinyl ether lithium (7.38 ml, 3.69 mmol) in THF via a cannula dropwise over 25 min. The reaction mixture was stirred for an addition 40 min at −78° C. before wet THF (THF/Water 10/1, 10 ml) was added. The reaction was allowed to warm to room temperature. The mixture was cooled, aqueous potassium carbonate (saturated, 10 mL) was added and the mixture was extracted with ethyl acetate (3×20 mL). The combined organic fractions were washed with brine (saturated, 30 mL), dried, filtered and the solvent was evaporated under reduced pressure to give the title compound. The crude product was used directly without further purification in the next step.
