実験手順

1,4-dioxane (7.5 mL) and manganese (IV) dioxide (447 mg, 5.14 mmol) were added to crude (2,4-dichloro-3-phenylquinolin-6-yl)(3-methylisoxazol-5-yl)methanol (Intermediate 3: step a, 1.03 mmol assuming theoretical yield in prior step). The resulting black suspension was heated in a 100° C. oil bath in a sealed tube for 3 hours then cooled to room temperature. The mixture was then diluted with DCM, and filtered through Celite®. The filtrate was concentrated and the residue was purified by flash column chromatography (silica gel, 3-15% EtOAc-heptane) to afford slightly impure title compound which was used without further purification.
