Procedure

To a solution of the product from Example 179F (1.06 g, 1.16 mmol) in CH2Cl2 (40 mL) and H2O (2 mL) was added 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) (0.316 g, 1.393 mmol) in several portions. The mixture was stirred at rt for 20 min and was washed with saturated. aq. NaHCO3. The organic layer was dried over Na2SO4, filtered and concentrated in vacuo. The crude product was purified by column chromatography on silica gel using a solvent gradient of 0-25% EtOAc in hexane to give the title compound (0.53 g, 57%).
