    • 3 (0.45 mmol) and CsF (1.2 mmol) were added rapidly. The reaction was carried out at 85 °C and monitored by TLC (7:1 P.E./EtOAc eluent). After total conversion of the triflate (about 0.8 h later), the reaction mixture was filtrated through a short pad of silica gel to remove indiscerptible materials, and then evaporated under vacuum to get rid of the solvent, and the residue was purified by chromatography (15:1 P.E./EtOAc eluent) to give 4a (about 49 mg) in 60% yield.
