Acetic Acid → HCID 68574385, Verbindung

6-Chloro-4-phenyl-quinolin-2-ylamine (CAS 51478-40-1, 750 mg, 2.94 mmol) was dissolved in 40 mL dichloromethane. 2-Methoxybenzaldehyde (481 mg, 3.54 mmol) and acetic acid (354 mg, 5.9 mmol) were added. The reaction mixture was stirred at room temperature for 2 h. Sodium triacetoxy borohydride (1.39 g, 6.59 mmol) was added and stirring was continued overnight. The reaction mixture was quenched by addition of 100 mL sat. sodiumbicarbonate solution. The mixture was extracted three times with dichloromethane (100 mL each). The organic phases ware pooled, dried with sodium sulfate, filtered and evaporated. The residue purified by flash chromatography on silica gel (cyclohexane/ethyl acetate 100:0->80:20 gradient). (6-Chloro-4-phenyl-quinolin-2-yl)-(2-methoxy-benzyl)-amine was obtained as an off-white solid (595 mg, 54%), MS: m/e=375.1 (M+H+).
