Phenacyl bromide → HCID 1794747, compound

Participants

Reaction Steps

A mixture of 8-benzoyl-7-hydroxy-4-methyl-chromen-2-one (30 mg, 0.1 mmol), 2-bromoacetophenone (22 mg, 0.11 mmol), and K2CO3 (143 mg, 1.03 mmol) in CH3CN (5 mL) was refluxed overnight. The reaction mixture was filtered and the filtrate was concentrated. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=3/1 then hexane/ethyl acetate=1/1, Rf=0.33 hexane/ethyl acetate=1/1) to provide 8-benzoyl-4-methyl-9-phenyl-furo[2,3-h]chromen-2-one as a yellow solid (71% yield).
