実験手順

A solution of n-BuLi (2.5 M in hexanes, 0.68 mL, 1.7 mmol) was added dropwise by syringe to a solution of 6-bromo-4-chloro-2-methoxy-3-((6-(trifluoromethyl)pyridin-3-yl)methyl)quinoline (0.404 g, 0.936 mmol, Intermediate 45: step d) in dry THF (17 mL) in a dry ice-acetone bath. After 1-2 minutes, a solution of (2,6-dimethylpyridin-3-yl)(1-methyl-1H-1,2,3-triazol-5-yl)methanone (0.346 g, 1.601 mmol, Intermediate 19: step b) in dry THF (8 mL) was added dropwise. The reaction was stirred for 10 minutes, then was moved into an ice bath and allowed to warm to ambient temperature. The reaction was quenched with saturated aqueous ammonium chloride. The mixture was partitioned between water and dichloromethane. The separated aqueous phase was further extracted with dichloromethane. The organic phase was dried (Na2SO4), filtered, and concentrated. The crude product was purified by flash column chromatography (silica gel, 0-4% MeOH-DCM) to provide the title compound. 1H NMR (400 MHz, CDCl3) δ 8.71 (d, J=1.7 Hz, 1H), 8.11 (d, J=2.1 Hz, 1H), 7.80 (d, J=8.7 Hz, 1H), 7.76 (dd, J=8.1, 1.6 Hz, 1H), 7.56 (d, J=8.0 Hz, 1H), 7.40 (dd, J=8.8, 2.2 Hz, 1H), 6.96-6.90 (m, 2H), 6.83 (s, 1H), 5.01 (s, 1H), 4.33 (s, 2H), 4.09 (s, 3H), 3.91 (s, 3H), 2.51 (s, 3H), 2.32 (s, 3H); MS m/e 569.0 [M+H]+.
