2-Bromopyridine → HCID 15123334, compound

Participants

Reaction Steps

To a stirred solution of 2-bromopyridine (10 mmol) in THF (120 mL) at −78° C. under argon, 2.5 M n-butyl lithium solution in hexane (4.5 mL, 11.25 mmol) was injected over 5 min. After 25 min, 1-benzylpiperidone (10 mmol) was added neat. After 30 min, the mixture was quenched by addition of aqueous NH4Cl solution (50 mL). The mixture diluted with ethyl acetate (200 mL), washed with brine (150 mL), dried (Na2SO4). Solvent was evaporated and the residue was purified by column chromatography (silica gel, EtOAc/Hexane from 20% to 60%) to give the desired product(1.78 g, 66.41% ). 1H-NMR was consistent with the structure.
