実験手順

14 g (0.1 mole) of N-acetyl-4-piperidone and 32 g (0.3 mole) of benzaldehyde in 150 ml of ethanol are cooled to 15° and treated dropwise with 33 ml of concentrated HCl, refluxed for 6 hours, and stored overnight at room temperature. The light yellow solid is filtered, washed with ethanol, then with ether and air-dried, weight 26 g (83%), mp. 273°-275°(dec.).
