(4-Chlorophenyl)(2,4-dichloro-3-phenylquinolin-6-yl)(1-methyl-1H-imidazol-5-yl)methanol (100 mg, 0.202 mmol, Example 65), N-(2-hydroxylethyl)propionamide (34.2 μL, 0.303 mmol), toluene (2 mL), and sodium hydride (60% dispersion in mineral oil, 32.3 mg, 0.808 mmol) were combined in a round bottom flask under an N2 atmosphere. The reaction solution was heated to reflux and refluxed overnight. The reaction solution was cooled to room temperature then transferred to a separatory funnel with EtOAc dilution, and extracted with saturated, aqueous NH4Cl then saturated, aqueous NaHCO3 solutions. The organic phase was separated, then dried over MgSO4, filtered and concentrated under reduced pressure. The crude product was purified by flash column chromatography (silica gel, 0-10% DCM/MeOH) then via reverse phase chromatography using acetonitrile with 0.05% trifluoroacetic acid in water as eluent. The fractions from the purification containing the desired product were transferred to a separatory funnel with EtOAc and extracted with a saturated, aqueous NaHCO3 solution. The aqueous layer was separated, extracted with EtOAc, then the combined organic phases were dried over MgSO4, filtered and concentrated under reduced pressure to provide the title compound.
