실험 절차

A mixture of 3-(4-(1H-pyrazol-1-yl)benzyl)-6-bromo-2,4-dichloro-8-methylquinoline (393 mg, 0.880 mmol, Intermediate 19: step a) and (4-chlorophenyl)(1-methyl-1H-imidazol-5-yl)methanone (194 mg, 0.880 mmol, Intermediate 1: step b) in dry degassed THF (16 mL) was cooled to −78° C. and n-BuLi (1.6 M in hexane, 0.5 mL, 0.8 mmol) was added over 1.5 minutes. Stirring was continued at −78° C. for 10 minutes and the dry ice acetone bath was replaced with an ice water bath. Stirring was continued for 1 hour and the reaction mixture was quenched with saturated aqueous NH4Cl solution. EtOAc was added and the layers were separated and the aqueous mixture again extracted with EtOAc. The combined organic extracts were dried over MgSO4, filtered, and the solvents were removed under reduced pressure. Purification using flash column chromatography (5% MeOH in dichloromethane) yielded the substantially pure title compound. MS (ESI) 588.2.
