Sodium Sulfite → 5-(2-Hydroxyethyl)-2-{[3-(trifluoromethyl)phenyl]oxy}benzonitrile

Participants

Reaction Steps

To a stirred a solution of 9-BBN (10.37 mL, 5.19 mmol) in dry THF (30 mL) was added dropwise a solution of 5-ethenyl-2-{[3-(trifluoromethyl)phenyl]oxy}benzonitrile (1 g, 3.46 mmol) in THF (30 mL) under nitrogen at 0° C. for 0.5 h. The mixture was then allowed to warm to room temperature and stirring continued for 2 h. Na2SO3 was added to quench the reaction. Purification via flash chromatography then afforded the title compound (546 mg, 1.777 mmol, 51.4% yield).
