Reaction Steps

(4-Chloro-3-(4-fluorobenzyl)-2-methoxyquinolin-6-yl)(1,2-dimethyl-1H-imidazol-5-yl)methanol (224.2 mg, 0.526 mmol, Intermediate 46: step a), 1,4-dioxane (2.6 mL) and activated MnO2 (232 mg, 2.67 mmol) were combined in a round-bottom flask and the mixture was refluxed under a positive pressure of N2 overnight. The reaction was allowed to cool to ambient temperature, then filtered through Celite® and rinsed with dichloromethane. The filtrate was washed with water, and the aqueous layer was extracted with additional dichloromethane. The combined organic layers were dried (Na2SO4), filtered, and concentrated to provide the title compound which was used without further purification.
