Reaction Steps

To a mixed solution of the compound (1.5 g, 4.2 mmol) obtained in Example 36a in ethanol/tetrahydrofuran (v/v=1/1, 20 mL) was added palladium-carbon (10% wet., 150 mg), and the mixture was stirred at room temperature for 3 hr under a hydrogen atmosphere (1 atm). Palladium-carbon was removed by filtration and the solvent was evaporated under reduced pressure to give a crude title compound.
