To a cooled (ice bath) and stirred suspension of 2-(2-methoxy-benzylamino)-quinoline-5-carbonitrile (289 mg, 1.0 mmol) in diethylether (3 ml) and THF (1 ml) was added drop wise a 1M solution of 4-fluorophenyl-magnesium bromide (4 ml, 4.0 mmol), the reaction mixture was heated under reflux conditions for 24 h and poured into ice-water (15 ml). 2N HCl (5 ml) was added, the mixture was stirred at room temperature for 10 min, 3 N NaOH (5 ml) was added and the mixture was extracted with ethyl acetate (2×40 ml). The combined organic layers were washed with brine (2×20 ml), dried (MgSO4) and evaporated. The crude product was purified by flash chromatography (ethyl acetate/heptane) on silica gel and crystallization (dichloromethane/hexane) to yield the title compound as white solid (159 mg, 41%).
