実験手順
A solution of Intermediate 6 (120 mg) obtained in Example 9, Step A in ethanol (2 ml) is added with 10% palladium/activated carbon (90 mg, Wako Pure Chemical Industries), and the mixture is stirred at room temperature for 72 hours under a hydrogen gas atmosphere. The atmosphere is replaced with nitrogen gas, and then the insoluble matters are removed by filtration through Celite. The solvent is evaporated under reduced pressure, and the residue is purified by silica gel chromatography (n-hexane:ethyl acetate=2:1) to obtain the title compound (195 mg (predictive yield)).
