A solution of n-butyllithium in hexanes (2.5 M, 0.47 mL, 1.2 mmol) was added dropwise to a stirring solution of 3-(4-(1H-pyrazol-1-yl)benzyl)-6-bromo-4-chloro-2-methoxyquinoline (500 mg, 1.2 mmol, Intermediate 10) in tetrahydrofuran (9 mL) at −78° C. After 5 minutes, a solution of (2,4-dimethylthiazol-5-yl)(1-methyl-1H-1,2,3-triazol-5-yl)methanone (259 mg, 1.2 mmol, Intermediate 23: step b) in tetrahydrofuran (2 mL) was added dropwise. After 2 minutes, the flask was placed into an ice-water bath. After 90 minutes, water (4 mL) was added and the mixture was allowed to warm to 23° C. The biphasic mixture was partitioned between saturated aqueous sodium chloride solution (20 mL) and ethyl acetate (50 mL). The layers were separated. The organic layer was dried with sodium sulfate and the dried solution was filtered. Silica gel (5 g) was added to the filtrate and the mixture was concentrated by rotary evaporation to afford a free-flowing powder. The powder was loaded onto a silica gel column for flash column chromatography purification. Elution with 40% ethyl acetate-hexanes initially, grading to 90% ethyl acetate-hexanes provided the title compound as an off-white foam. 1H NMR (400 MHz, CDCl3) δ ppm 8.15 (d, J=2.2 Hz, 1H), 7.89-7.81 (m, 2H), 7.67 (d, J=1.7 Hz, 1H), 7.59-7.54 (m, 2H), 7.54-7.48 (m, 1H), 7.41-7.34 (m, 2H), 7.23 (s, 1H), 6.45-6.41 (m, 1H), 4.32 (s, 2H), 4.11 (s, 3H), 3.91 (s, 3H), 3.71 (s, 1H), 2.58 (s, 3H), 2.15 (s, 3H); MS (ESI): mass calcd. for C29H26ClN7O2S, 571.2. m/z found, 572.1 [M+H]+.
