6-Bromo-2,4-dichloro-3-phenylquinoline (2.00 g, 4.62 mmol, Intermediate 3: step c) was dissolved in THF (250 mL) in a dry round bottom flask under an N2 atmosphere, then cooled to −45° C. in a dry ice acetone bath. n-BuLi (1.6 M in hexanes, 3.18 mL, 5.08 mmol) was then added dropwise via syringe over approximately 2 minutes and the resulting mixture was allowed to stir at that temperature for an additional 2 minutes. (2,6-Dimethylpyridin-3-yl)(1-methyl-1H-1,2,3-triazol-5-yl)methanone (1.10 g, 5.08 mmol, Intermediate 19: step b) in THF (15 mL) was then added to the reaction vessel via cannula over approximately 5 minutes. The reaction solution was stirred at −78° C. for approximately 5 minutes, then the dry ice bath was removed and replaced with an ice water bath and stirred at 0° C. for approximately 1 hour. The reaction was then quenched with a saturated, aqueous NH4Cl solution, then transferred to a separatory funnel with EtOAc. The organic phase was separated, then the aqueous layer was back extracted with EtOAc and the combined organic phases were dried over MgSO4, filtered and concentrated under reduced pressure. The crude product was purified by flash column chromatography (silica gel, 0-10% DCM/(10% of a 2 M NH3 MeOH in DCM)) then further purified via reverse phase chromatography using acetonitrile with ammonium hydroxide in water as eluent to afford the title compound.
