To a solution of [5-[6-amino-5-(1-isopropyltriazol-4-yl)-3-pyridyl]-2-fluoro-phenyl]-morpholino-methanone (150 mg, 0.365 mmol) in THF (10.0 mL) was added BF3.Et2O (0.25 mL, 1.827 mmol) at 0° C. and stirred for 30 min. After 30 min, NaBH4 (69 mg, 1.827 mmol) was added at 0° C. and stirred at room temperature for 18 h. After cooling to 0° C., quenched with MeOH (2 mL) and heated to reflux for 6 h. The reaction mixture was diluted with EtOAc (20 mL), washed with water (20 mL), dried over anhydrous Na2SO4 and solvent was evaporated under reduced pressure. Crude compound was purified by column using 100-200 mesh silica gel. The column was eluted with 5% MeOH in DCM to afford 60 mg (yield: 41.66%) of the title compound as white solid.
