4-Methoxybenzylamine → (3-Bromo-6-fluoro-pyridin-2-ylmethyl)-(4-methoxy-benzyl)-amine

Participants

Reaction Steps

To a solution of 3-bromo-2-bromomethyl-6-fluoro-pyridine (2.70 g, 10.0 mmol, 1.0 equiv) in dichloromethane (20 mL) was added a solution of 4-methoxybenzylamine (2.74 g, 20.0 mmol, 2.0 equiv) in dichloromethane (5 mL) and the reaction mixture was stirred at ambient temperature for 3 h. The reaction mixture was diluted with dichloromethane, washed with H2O, dried (MgSO4), filtered and concentrated under reduced pressure. The crude product was purified by column chromatography (SiO2, eluted with petrol—EtOAc 0-50%) to afford (3-bromo-6-fluoro-pyridin-2-ylmethyl)-(4-methoxy-benzyl)-amine (1.2 g). MS: [M+H]+=326.
