実験手順

n-BuLi (1.6 M in hexane, 2.19 mL, 3.50 mmol) was added over approximately 1 min to a solution of 6-bromo-4-chloro-3-(3-fluorophenyl)-2-methoxy-8-methylquinoline (1.40 g, 3.68 mmol, Intermediate 52) in THF (5 mL) under argon at −78° C. After 1 min, a solution of (1-methyl-1H-imidazol-5-yl)(6-(trifluoromethyl)pyridin-3-yl)methanone (939 mg, 3.68 mmol, Intermediate 15, step c) in 5 mL THF under argon was added via cannula. The resulting mixture was stirred at −78° C. for 10 min, then transferred to an ice water bath and stirred 30 min. The reaction was quenched by addition of saturated aqueous NH4Cl, diluted with water and extracted with EtOAc (3×). The organic phase was dried (Na2SO4), filtered, and concentrated. The residue was purified by flash column chromatography (silica gel, 45-60% CH3CN in [2% conc. aqueous NH4OH in DCM, aqueous phase removed]) to afford the title compound as a white foam.
