Versuchsvorschrift

To a solution of (3-chloro-2-fluoro-phenyl)-acetonitrile (1.48 g, 8.8 mmol) in anhydrous THF (20 mL) was added a solution of borane (20 mL, 1M in THF) dropwise. The resulting reaction mixture was heated at reflux temperature for 2 hours. After cooling to room temperature, MeOH was added and the mixture was stirred at room temperature for additional 30 min. After removal of volatiles under reduced pressure, desired title product (1.30 g, 90%) was obtained as oil. MS: 174.0 (M+H)+.
