실험 절차

To a solution of 3-(3-bromo-5-fluorophenyl)-3-hydroxypropanenitrile (2.50 g, 8.65 mmol) in THF (16.0 mL) was added borane methyl sulfide (1.20 g, 15.7 mmol). The mixture was heated to reflux for 2 h. After cooling to room temperature, saturated aqueous NaHCO3 (10 mL) was added and the mixture was stirred for 1 h. The THF was removed under reduced pressure and the remaining aqueous portion was extracted with ethyl acetate (2×60 ml). The extract was dried (Na2SO4) and concentrated to give 3-amino-1-(3-bromo-5-fluorophenyl)propan-1-ol that was used in following reaction without further purification.
