The reaction mixture was filtered and the solvent was removed in vacuo. The residue was dissolved in methylene chloride and washed with aqueous NaHCO3. The organic layer was separated and the solvent was evaporated. The crude product was purified by flash chromatography eluting with CH2Cl2/MeOH to give 0.7 g of the title compound.
