Yield: 79%
Reaction Conditions:
with piperidine in ethanol for 6 h;Reflux;
Steps:
1 Synthesis of coumarin derivatives represented by formula (III)
The 8-hydroxy-nonalonidine-9-carbaldehyde (0.6518g, 3mmol), ethyl acetate (0.7748g, 3mmol) and piperidine (0.5ml, 3mmol) represented by formula (II) were dissolved in 24mL of anhydrous In ethanol.The mixture was heated and refluxed for 6 hours, then cooled to room temperature.The suspension was then collected by filtration and washed with cold absolute ethanol.Finally, the product was dried under vacuum to obtain orange crystals, and the coumarin derivative represented by formula (III) (0.6715 g, 79%) was obtained.
