実験手順
2-Acetyl-4-(4-pyridyl)cyclohexanone (1.65 g) and cyanoacetamide (0.64 g) were dissolved in ethanol, and a small amount of piperidine was added. The reaction mixture was heated under reflux for 7 hours. After the reaction was completed, deposited crystals were filtered out to obtain 0.7 g of 4-cyano-2,3,5,6,7,8-hexahydro-1-methyl-3-oxo-7-(4-pyridyl)isoquinoline.
