In a nitrogen atmosphere, to a suspension of palladium hydroxide (20% by weight; 18 mg) in methanol (1 ml), a solution of Compound 27 (190 mg, 0.323 mmol) in methanol (1.5 ml) was added; after the nitrogen atmosphere was replaced with a hydrogen atmosphere, stirring was conducted at room temperature for 1 hour. After a nitrogen atmosphere was restored, insoluble matter was separated by filtration on Celite and washed with methanol. Concentration under reduced pressure was conducted to yield a crude product of Compound 28.
