Procedure

2-(2-Methoxy-benzylamino)-quinoline-6-carbaldehyde (663 mg, 2.27 mmol) was dissolved in 25 mL methanol and sodium borohydride (343 mg, 9.03 mmol) was added. The reaction mixture was refluxed for 3 h. The solvent was evaporated off. The residue was taken up in 100 mL water and extracted three times with ethyl acetate (100 mL each). The organic phases ware pooled, dried with sodium sulfate, filtered and evaporated. The crude product was recrystallized from dichloromethane. [2-(2-Methoxy-benzylamino)-quinolin-6-yl]-methanol was obtained as a white solid (369 mg, 59%), MS: m/e=295.3 (M+H+).
