The mixture was stirred at r.t. for 0.25 h. The mixture was cooled to 0° C. Trichloroacetonitrile (11 mmol) was added. The mixture was allowed to warmed to r.t. over 1 h. The mixture was diluted with EtOAc and washed with NaHCO3. The organic extract was dried (anhyd. MgSO4) and concentrated under reduced pressure to give an oil. Chromatography (10% Acetone/EtOAc) gave the title compound.
