Reaction Steps

The solution of Example 265B (0.8 g, 3.2 mmol) in EtOH (15 mL) was hydrogenated in the presence of Pd/C (320 mg). The resulting mixture was stirred at room temperature for 12 hours. After the filtration to remove Pd/C, the filtrate was concentrated under reduced pressure to give title compound (780 mg, 92% yield) as a colorless oil, which was used in the next step without further purification. 1H NMR: (400 MHz, CDCl3): δ 3.68-3.38 (m, 2H), 3.33-3.03 (m, 2H), 2.77-2.33 (m, 3H), 2.26-2.12 (m, 2H), 1.90-1.62 (m, 4H), 1.49 (s, 9H).
