Reaction Steps

A solution of ethyl 2-[6,7-bis(hydroxymethyl)-2-oxo-4-phenyl-2H-chromen-3-yl]acetate (150 mg) in dichloromethane (3 ml) was combined with manganese dioxide (1.5 g), and stirred at room temperature overnight. After the catalyst was filtered off, the filtrate was concentrated under reduced pressure to obtain the residue, which was recrystallized from THF to obtain the title compound (98 mg, yield: 66%).
