Procedure

Sodium hydride (200 mg, 5 mmol; washed three times with hexane) was treated with 1-decanol (12 mL, 63 mmol) for 1 hour at room temperature. Acrylonitrile (10 mL, 152 mmol) was added dropwise and the resulting paste warmed to 60° C. for 2 hours. After cooling to room temperature, the paste was dissolved in diethyl ether and washed with copious water, one portion of brine, dried over magnesium sulfate, filtered and concentrated. Chromatography of the crude residue on silica gel using 25-75 ethyl acetate-hexane as eluant gave the title compound (5.5 g) as a water-white liquid. The structure was supported by NMR, infrared spectroscopy, elemental analysis and mass spectroscopy.
