Participants

Reaction Conditions

Reaction Steps

To a stirred solution of isobutyraldehyde (6.3 mL, 69.3 mmol), hydroquinone (25 mg) and acrylonitrile (5.7 mL, 86.7 mmol) in 1,4-dioxane (25 mL) was added 5% sodium hydroxide (4.6 mL). The reaction was heated at 65° C. for 2.5 hours and then stirred at ambient temperature for 16 hours. The dioxane was removed in vacuo and the residue was taken up in dichloromethane (80 mL). The dichloromethane was washed with water (3×80 mL), dried (magnesium sulfate), concentrated in vacuo and then distilled to afford the title compound (5.4 g, 63%) as a colorless liquid; bp 70° C. (0.8 mm);
