Versuchsvorschrift

To a flask containing 6-bromo-4-chloro-2-methoxy-3-(4-(trifluoromethyl)benzyl)quinoline (1.45 g, 3.37 mmol, Intermediate 5: step d) was added THF (25 mL) and the solution was cooled to −75° C. n-BuLi (2.5 M in hexanes, 1.3 mL, 3.25 mmol) was then added dropwise. After 2 minutes, 1-methyl-1H-1,2,3-triazole-5-carbaldehyde (580 mg, 5.22 mmol, in 3 mL THF) was introduced. The reaction mixture was allowed to warm to −20° C. over 45 minutes at which time the reaction was quenched with aqueous NH4Cl solution. The aqueous portion was extracted with EtOAc (5×40 mL) and the combined organics were washed with brine, dried over MgSO4, filtered and concentrated to dryness. Chromatography on silica gel (5% CH3CN-DCM increasing to 30% CH3CN+2% MeOH) provided the title compound as an off white amorphous solid.
