With diisobutylaluminium hydride In tetrahydrofuran; toluene at 0 - 20℃; for 2h; | Preparation of A17 General procedure: To a solution of ester in THF is added DIBAL-H dropwise at 0 °C. After stirring at room temperature for 2 hours, water, 15% NaOH solution, water, and anhydrous sodium sulfate are added sequentiallly at 0 °C. The resulting slurry is stirred at room temperature for 1 hour and then filtered. The filter cake is washed with EA and the filtrate is concentrated.Following Procedure D using 13 (819 mg, 3.17 mmol), THF (5 mL), DIBAL- H (1.5 M in toluene, 8.4 mL, 12.6 mmol), then quench with water (0.50 mL), 15% NaOH solution (0.50 mL), water (1.26 mL), and anhydrous sodium sulfate (5 g), and purify with silica gel column chromatography (EA:PE = 1 : 1) to give A17 as a white solid (610 mg, 89% yield).
