2-Chloro-3-quinolinecarboxaldehyde (2.0 g, 10.4 mmol), ethylamine (2M in MeOH, 5.2 mL, 10.4 mmol), and acetic acid (0.65 mL, 11.4 mmol) were combined in MeOH (15 mL) and stirred at room temperature for 30 minutes until all materials were completely dissolved. Sodium cyanoborohydride (1.31 g, 20.9 mmol) was added portionwise over 5 minutes, and the reaction was stirred for 1 hour. The mixture was worked-up with saturated aqueous NaHCO3 and extracted with CH2Cl2, and the residue was purified by silica gel chromatography (0-5% MeOH in CH2Cl2) to give the title compound.
