Procedure
A mixture containing (2,6-dimethylpyridin-3-yl)(1-methyl-1H-1,2,3-triazol-5-yl)methanol (9.8 g, 44.9 mmol, Intermediate 19: step a) and manganese dioxide (18.8 g, 184 mmol) in dry dioxane (225 mL) was heated to 100° C. with stirring. After 1 hour, the mixture was cooled to 40° C. The cooled mixture was filtered through a 2 cm pad of Celite® and rinsed with tetrahydrofuran (100 mL). The filtrate was concentrated to provide the title compound as an off-white solid.
