Reaction Steps

(6-Bromo-quinolin-2-yl)-(2-methoxy-benzyl)-amine (2.0 g, 5.83 mmol) was dissolved in 100 mL tetrahydrofurane. n-Butyllithium solution (1.6 M in hexane, 9.1 mL, 14.6 mmol) was slowly added at −78° C. The reaction mixture was allowed to warm to −10° C. and stirred at this temperature for 45 min. The reaction mixture was then cooled again to −78° C. and dimethylformamide (1.07 g, 14.6 mmol) was added. The mixture was then slowly warmed up and quenched with 200 mL water at 5° C. The solvent was evaporated off. The residue was extracted three times with ethyl acetate (200 mL each). The organic phases ware pooled, dried with sodium sulfate, filtered and evaporated. The residue was purified by flash chromatography on silica gel (cyclohexane/ethyl acetate 100:0->50:50 gradient). 2-(2-Methoxy-benzylamino)-quinoline-6-carbaldehyde was obtained as a light yellow solid (683 mg, 40%), MS: m/e=293.1 (M+H+).
