Versuchsvorschrift

A solution of n-BuLi (2.5 M in hexanes, 0.095 mL, 0.238 mmol) was added dropwise by syringe to a solution of 3-(4-(1H-pyrazol-1-yl)benzyl)-6-bromo-4-chloro-2-methoxyquinoline (105.5 mg, 0.246 mmol, Intermediate 16) in dry THF (2.5 mL) in a dry ice-acetone bath. After 1.5 minutes, a solution of commercially available (4-fluorophenyl)(pyridin-3-yl)methanone (58.7 mg, 0.292 mmol) in dry THF (0.2 mL) was added dropwise. The reaction mixture was stirred for 5 minutes in a dry ice-acetone bath, then the reaction flask was placed into an ice-water bath. After 10 minutes, the mixture was warmed to room temperature and the reaction was quenched with methanol and water. The mixture was partitioned between water and ethyl acetate. The separated aqueous phase was further extracted with ethyl acetate. The organic phase was dried (Na2SO4), filtered, and concentrated. The crude product was purified by flash column chromatography (silica gel, 10-50% EtOAc-Hexanes followed by 0-10% MeOH-DCM) to provide the title compound as a white solid. 1H NMR (400 MHz, CDCl3) δ ppm 8.50-8.48 (m, 1H), 8.43 (dd, J=4.8, 1.6 Hz, 1H), 8.02 (d, J=2.1 Hz, 1H), 7.83 (d, J=2.4 Hz, 1H), 7.77 (d, J=8.8 Hz, 1H), 7.67-7.64 (m, 2H), 7.55-7.52 (m, 2H), 7.50 (dd, J=8.8, 2.2 Hz, 1H), 7.33 (d, J=8.6 Hz, 2H), 7.26-7.20 (m, 3H), 7.03-6.96 (m, 2H), 6.42-6.40 (m, 1H), 4.28 (s, 2H), 4.07 (s, 3H); MS m/e 551.2 [M+H]+.
