Procedure

Sodium hydride (55-65% dispersion in mineral oil, 220 mg, 5.50 mmol) was added to a solution of (4-chloro-2-methyl-quinolin-7-yl)-methanol (example 2c, 1.10 g, 5.30 mmol) and 4-fluorobenzonitrile (642 mg, 5.30 mmol) in N,N-dimethylformamide (20 mL), and the resulting mixture was stirred at 50° C. for 3 h. After cooling the mixture was partitioned between sat. aq. ammonium chloride solution and dichloromethane, the organic layer was separated, washed with brine, dried (MgSO4), and evaporated. Chromatography (SiO2, dichloromethane/methanol 19:1) yielded the title compound (1.28 g, 78%). Yellow solid, ISP-MS: m/e=309.3 ([M+H]+).
