Reaction Steps
In a flask equipped with a water separator are placed 7 g of 2-pyridyl acetonitrile, 12.8 g of isobutyraldehyde, 0.9 ml of acetic acid, 0.18 ml of piperidine and 250 ml of dry benzene. The mixture is heated under reflux for 3 hours. After cooling, the reaction mixture is washed with water, the organic phase is dried over sodium sulfate then the solvent is evaporated to dryness.
