In a flame-dried seal tube reaction vial, under argon atmosphere, add 2-(6-Chloro-pyridin-3-yl)-propan-2-ol (750 mg, 4.375 mmol), 2-(dicyclohexylphosphino)-biphenyl (307 mg, 0.875 mmol) and then add LiN(TMS)2 (1M in THF, 13.5 mL, 13.5 mmol). Seal the tube and heat it up to 90° C. for 18 hours. The dark reaction mixture was then diluted with EtOAc (10 mL). HCl (2M) (10 drops) was added with stirring. The reaction mixture was then concentrated and loaded onto ISCO separation column and eluted with 5% MeOH/(1/1 EtOAC/Hex) to afford 2-(6-Amino-pyridin-3-yl)-propan-2-ol as solid (635 mg, yield 95%).
