実験手順

To a solution of the product of Step A in 4 mL DMF was added 0.125 g (0.698 mmol) of 1-bromopinacolone and 0.455 g (1.39 mmol) of Cs2CO3. The reaction mixture was stirred at room temperature for 1 h, then partitioned between EtOAc and saturated aqueous NaHCO3 solution. The organic layer was separated, washed with aq. NaHCO3, brine, dried (Na2SO4), filtered and evaporated. The residue was purified on a silica gel flash chromatography column eluted with 0–75% EtOAc-hexane. Evaporation of the purified fractions and drying in vacuo afforded the title compound.
