A mixture of Compound 25 (3.96 g, 10.8 mmol) and 10% palladium on carbon (600 mg) in abs. methanol (100 mL) was hydrogenated at 1 atm for 12 hr. The hydrogen was replaced with nitrogen, the reaction was filtered and concentrated in vacuo. Chromatography of the residue on silica gel (elution with 20% ethyl acetate:hexanes) provided 2.72 g of Compound 26.
