Reaction Conditions

Reaction Steps

To a stirred solution of 83.27B (0.585 g, 2 mmol) in THF (20 mL) at 0° C. was added borane-THF (4 mL, 4 mmol, 1.0M). The reaction was warmed to 23° C. and stirring was continued for four hours. The reaction mixture was then concentrated in vacuo. The reaction was diluted with 1N HCl and 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 (0-40% EtOAc in hexanes) to yield 83.27C as a colorless oil (0.485 g, 87% yield).
