Procedure

To a suspension of (36) (6.3 g, 31 mmol) in a mixture of MeOH (60 ml) and THF (30 ml) was added 5% palladium on activated carbon (300 mg) and the mixture was hydrogenated at ambient pressure for 1 hr. The mixture was filtered and concentrated under reduced pressure. The residue was purified by column-chromatography on silica gel using a mixture of hexane and ethylcetate (3:1) as the eluent to give (37) (5.1 g, 96%).
