Procedure

A solution of n-BuLi (2.5 M in hexanes, 1.25 mL, 3.12 mmol) was added dropwise by syringe to a solution of 1-methyl-1H-1,2,3-triazole (268 mg, 3.22 mmol) in dry THF (32 mL) in a dry ice-methanol bath. The suspension was stirred for 30 minutes, slowly allowing the reaction mixture to warm to −10° C. (4-Chloro-2-methoxy-3-((6-(trifluoromethyl)pyridin-3-yl)methyl)quinolin-6-yl)(1,2-dimethyl-1H-imidazol-5-yl)methanone (0.500 g, 1.05 mmol, Intermediate 45: step f) in dry THF (5 mL) was added to the mixture via syringe and the resulting mixture was allowed to warm to ambient temperature overnight. The reaction was quenched with water. Brine was added and the aqueous mixture was extracted with ethyl acetate. The combined organic layers were dried (Na2SO4), filtered, and concentrated. The crude product was purified by flash column chromatography (silica gel, 0-8% MeOH-DCM) to provide the title compound. 1H NMR (500 MHz, CDCl3) δ 8.69 (d, J=1.7 Hz, 1H), 8.24 (d, J=1.9 Hz, 1H), 8.22 (s, 1H), 7.79-7.76 (m, 1H), 7.75 (d, J=8.7 Hz, 1H), 7.57 (d, J=8.1 Hz, 1H), 7.42 (dd, J=8.7, 2.0 Hz, 1H), 6.97 (s, 1H), 5.95 (s, 1H), 4.30 (s, 2H), 4.08 (s, 3H), 3.88 (s, 3H), 3.33 (s, 3H), 2.12 (s, 3H); MS m/e 557.8 [M+H]+.
