実験手順
To a solution of the product of Example 8B (610 mg, 1.857 mmol) in THF (19 mL) at 0° C. was added a 1M solution (in THF) of lithium aluminum deuteride (1.9 mL, 1.857 mmol) dropwise. After completion of addition the ice bath was removed and the reaction was stirred at room temperature for 3.5 hours under nitrogen atmosphere, monitoring by TLC (3:1 pentane:ethyl acetate). The reaction was then diluted with water and extracted with ethyl acetate (2 times). The combined organics were dried over Na2SO4, filtered, and concentrated under reduced pressure to obtain a clear oil (482 mg, 86% yield). The material was taken to the next step without further purification. 1H NMR (600 MHz, CDCl3): 7.33 (s, 4H), 4.56 (s, 2H), 0.89 (s, 9H), 0.06 (s, 6H).
