5-Fluoropyridin-2-amine (500 mg, 4.46 mmol) and 2,4-dimethoxybenzaldehyde (674 mg, 4.06 mmol) were stirred in dichloromethane (10 mL) at room temperature for 30 minutes. Sodium triacetoxyborohydride (1.3 g, 6.08 mmol) was added portion wise. The mixture was then stirred at room temperature for 18 hours before treatment with 1M aqueous sodium hydroxide solution (10 mL). The aqueous layer was separated and extracted with dichloromethane (10 mL). The combined organic layers were dried through a phase separating cartridge and evaporated to afford the title compound (1.2 g) as a brown solid.
