Piperidine → HCID 86637633, compound

Participants

Reaction Steps

4-hydroxy-1-naphtaldehyde (0.70 g (5.81 mmol)), 4-(dicyanomethylene)-2,6-dimethyl-4H-pyrane (1.0 g (5.81 mmol)), piperidine (0.50 g (5.81 mmol)), and ethanol (50 mL) were added to a 50-mL three-neck flask. The resultant was heated and refluxed under an argon atmosphere for 6 hours and then the solvent was removed under reduced pressure, followed by purification by column chromatography (SiO2, CHCl3:MeOH=10:1 (v/v)). Thus a desired compound was obtained (yield: 48.2%).
