Pyridine → 1-[2-(5-Bromo-pyridin-3-yl)-pyrrolidin-1-yl]-ethanone

참여 물질

반응 단계

To a solution of 3-bromo-5-(2-pyrrolidinyl)pyridine (200 mg, 0.881 mmol) and pyridine (0.2 mL, 1.96 mmol) in DCM (1 mL) in a 8-mL vial is added acetic anhydride (0.093 mL, 0.969 mmol) dropwise. The mixture is stirred at room temperature for 2.5 h. The mixture is concentrated. The resulting crude product is purified by normal phase chromatography using 0-4.5% MeOH in DCM as the gradient to afford 1-[2-(5-bromo-pyridin-3-yl)-pyrrolidin-1-yl]-ethanone (313 mg, 83% yield).
