실험 절차
A mixture of compound 9 (120 mg, 0.263 mmol), compound A (76 mg, 0.263 mmol) and K2CO3 (72.58 mg, 0.526 mmol) was heated under reflux in 25 ml of acetone for 3 hours. The reaction mixture was cooled to ambient temperature, filtered and the filtrate was evaporated to obtain crude residue which was purified by column chromatography using MeOH/DCM (15:85) as an eluent to obtain compound 10 as a yellow colored gummy material (75 mg). Yield: 40%.
