Benzoyl chloride → N-[2-(Benzo[1,3]dioxol-5-yl)-3-hydroxy-4-oxo-4H-chromen-6-yl]-benzamide

Participants

Reaction Steps

30 mg (101 pmol) of 6-amino-2-(benzo[1,3]dioxol-5-yl)-3-hydroxy-4H-chromen-4-one obtained in Example 24 was dissolved in 2 ml of methylenechloride, and the mixture was reacted with 10 molar equivalents of benzoylchloride and excess amount of potassium carbonate at room temperature for 10 hours. The resulting product was filtered, washed with methylenechloride and water, and dried to give 32 mg of the title compound in a yield of 79%.
