Procedure

To a solution of the compound of Example 10c (0.090 mmol) in 4.5 ml of dry methanol and 1.5 ml of dry ethyl acetate there is added 10% palladium-on-carbon (84.0 mg). The reaction mixture is degassed twice and is then stirred at ambient temperature under a hydrogen atmosphere (1 bar) for 24 hours. After 24 hours, more 10% palladium-on-carbon (42.0 mg) is added. The reaction mixture is degassed again and is then held under a hydrogen atmosphere for 24 hours. The mixture is filtered over Celite, and the solid is washed with methanol and with chloroform. After evaporating off the solvents and purifying the residue by chromatography on silica gel (cyclohexane/ethyl acetate: 3/2), the expected product is isolated.
