Reaction Steps

The compound (5.00 g, 24.7 mmol) obtained in step A was dissolved in tetrahydrofuran (100 ml), and the mixture was stirred under ice-cooling. Lithium aluminum hydride (1.87 g, 49.4 mmol) was gradually added at the same temperature, and the mixture was stirred at room temperature for 2 hr. After ice-cooling again, water (1.9 ml), 1N aqueous sodium hydroxide solution (3.8 ml) and water (1.9 ml) were gradually added in this order, and the mixture was stirred at room temperature for 1 hr. The insoluble material was filtered off through celite, and the obtained solution was concentrated under reduced pressure to give the title compound (4.89 g, yield 96%) as a pale-yellow oil.
