Reaction Steps
A mixture of compound 23e (0.532 mmol, 150 mg) and CuI (0.32 mmol, 60 mg) in DMF (1.5 mL) was heated at 110° C. for 5 h and then cooled to room temperature. The reaction was quenched with water and extracted with EtOAc. The organic layer was concentrated and purified by flash column chromatography (silica gel, 15% EtOAc/hexanes) to give compound 23f.
