Reaction Steps

The compound obtained in Example 12 (5.50 g, 9.7 mmol) was dissolved in methanol (60 ml). To the solution was added 10% palladium carbon (water content:50%, 2.2 g), and the mixture was subjected to catalytic hydrogenation reaction at room temperature for 16 hours. The catalyst was filtered off, and the filtrate was concentrated under reduced pressure to give the titled compound (4.11 g, 9.5 mmol, Yield 98%).
