A mixture of 11-6 (4.0 g, 13.9 mmol) and 10% Pd/carbon (4.0 g) in EtOH (100 mL) was stirred under a balloon of hydrogen for 4 h. Following filtration and evaporative removal of the solvent, the residue was chromatographed (silica gel, 70:28:2 chloroform/ethyl acetate/methanol) to give 11-7 as a white solid.
