Versuchsvorschrift

Acetonitrile (0.102 mL, 1.95 mmol) was dissolved in THF. Potassium 2,2-dimethylpropan-1-olate (3.44 mL, 5.85 mmol) was added, followed by addition of ethyl-2-methylcyclopropanecarboxylate (1.0 g, 7.80 mmol). After five minutes, the reaction mixture was quenched with 1N HCl and then partitioned with EtOAc. The organic layer was washed with water (3×), brine, dried over Na2SO4 and concentrated to give 3-(2-methylcyclopropyl)-3-oxopropanenitrile as an oil, which was used in the next step without further purification.
