Procedure

To a 100 mL flask containing (4-chloro-2-methoxy-3-(4-(trifluoromethyl)benzyl)quinolin-6-yl)(2,4-dimethyloxazol-5-yl)methanol (960 mg, 2.01 mmol, Intermediate 87: step a) was added 1,4-dioxane (50 mL) and activated MnO2 (900 mg, 10.3 mmol) at room temperature. The mixture was heated to 85° C. in an aluminum heating mantle under a nitrogen atmosphere. After 60 minutes, the contents were filtered through Celite® while the solution is still warm and rinsed with THF, and concentrated to give an off white solid. The crude material was triturated with Et2O to give a white solid.
