反应详情

To a stirred solution of T23.5 (0.293 g, 0.9 mmol) in THF (5 mL, 0.9 mmol) at 0° C. was added LAH in THF (2 mL, 2 mmol, 1.0M). The reaction was stirred for one hour and then 1N NaOH(aq) was added to quench the mixture. The reaction was extracted three times with EtOAc. After drying over anhydrous magnesium sulfate and filtering, the organic solvent was removed under reduced pressure and the product was then purified on silica gel (0-20% EtOAc in hexanes) to yield T23.6 as a colorless oil (0.260 g, 97% yield).
