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

참여 물질

반응 단계

Catalytic amount of acetic acid (0.3 mL) was added to a mixture of 3-bromoisonicotinaldehyde (200 mg, 1.075 mmol) and pyrrolidine (0.12 mL, 1.34 mmol) in DCE (20 mL) under nitrogen atmosphere and the resulting mixture was stirred at room temperature for 2.3 hours. This was followed by the addition of sodium triacetoxy-borohydride (342 mg, 1.612 mmol) at 0° C. The reaction mixture was stirred at room temperature overnight. The reaction was monitored by TLC (50% ethylacetate in hexane). The reaction mixture was washed with NaHCO3 solution and separated the layers. The organic layer was dried over Na2SO4 and concentrated to afford 250 mg of the product (96.52% yield).
