Acetic Acid → 3-Bromo-4-(pyrrolidin-1-ylmethyl)pyridine

참여 물질

반응 단계

Acetic acid (0.1 mL) was added to a stirred solution of 3-bromo-pyridine-4-carbaldehyde (220 mg, 1.18 mmol) and pyrrolidine (0.11 mL, 1.34 mmol) in DCE (15 mL) under nitrogen atmosphere and stirred at room temperature for 2 hours. This was followed by addition of NaBH(OAc)3 (342 mg, 1.612 mmol) at 0° C. over a period of 10 minutes. The resulting reaction mass was stirred for 12 hours at room temperature. The reaction was monitored by TLC (30% ethyl acetate in hexane). The reaction mixture was washed with NaHCO3 solution and extracted using ethyl acetate. The organic layer was dried over Na2SO4 and concentrated to afford 275 mg of the product (98.2% yield).
