Piperidine → 4',5,7-Trihydroxy-2-piperidinomethylisoflavone

Participants

Reaction Steps

4',5,7-Trihydroxy-2-bromomethylisoflavone (160 mg) was dissolved in 2 ml N,N-dimethylformamide, 100 mg piperidine was added to the solution, and the mixture was stirred at room temperature for three hours. The solvent was distilled off under reduced pressure, the residue was purified by silica gel column chromatography (chloroform:methanol=96:4), and the solid thus obtained was recrystallized from ethanol, giving 150 mg of 4',5,7-trihydroxy-2-piperidinomethylisoflavone.
