Reaction Steps
In an analogous fashion to 2-hydroxyethoxythioxanthone in Example 29, 7-hydroxyflavone (Aldrich) was reacted with ethylene carbonate and triethylamine to obtain 7-hydroxyethoxyflavone (83% yield). This product was dissolved in THF. One equivalent of VDM and several drops of DBU were added. The reaction mixture was stirred overnight.
