反应详情

To a stirred solution of T21.4 (0.350 g, 0.9 mmol) in THF (9 mL, 0.9 mmol) at 0° C. was added LAH in THF (2 mL, 2 mmol, 1.0M). The reaction was stirred for 1 hour. 1N NaOH(aq) was then added to quench the reaction. 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 T21.5 as a colorless oil (0.387 g, 120% yield).
