Versuchsvorschrift

To a stirred solution of T12.6 (0.300 g, 0.814 mmol) in THF (0.0587 g, 0.814 mmol) at 0° C. was added LAH (1.63 mL, 1.63 mmol, 1.0M). The resulting mixture was stirred for 4.5 hours. Next, 1N NaOH(aq) was added to quench the mixture. The reaction was extracted three times with EtOAc. The combined organic layers were dried over anhydrous magnesium sulfate and filtered. The organic solvent was removed under reduced pressure, and the product was purified on silica gel (0-20% EtOAc in hexanes) to yield T12.7 as a colorless oil (0.250 g, 90.2% yield).
