To a stirred solution of (5-bromo-2-pyridinyl)acetonitrile (0.26 g, 0.94 mmole), in THF (20 mL) at RT was added 1M BH3.THF (5 mL, 5.0 mmole). After 24 h, H2O (10 mL) wash added dropwise to the reaction solution followed by 1M HCl (10 mL). After 1 h, the reaction solution was made basic by addition of 6M NaOH (2 mL). The reaction contents were concentrated under vacuum and extracted with EtOAc (3×50 mL). The organic phase was dried over Na2SO4 and concentrated under vacuum affording the crude title compound as light orange solid which was used directly without further purification: LC-MS (ES) m/e 281 (M+H)+.
