Reaction Steps

To a solution of Compound 10 (0.55 g, 1.5 mmol) obtained in Example 10 in ethanol (5.5 mL) and acetone (8.0 m) was added 10% palladium-carbon (containing 50% of water) (0.11 g), and the mixture was subjected to a hydrogenation reaction at room temperature and ordinary pressure for 3 hours. After removal of the catalyst, the solvent was evaporated in vacuo from the filtrate to give Compound 20 (0.54 g, 100%) as a mixture of isomers in a pale yellow oil.
