Procedure

To a solution of methyl 5-(4-(1H-pyrazol-1-yl)benzyl)-3,4-dimethyl-2-vinylbenzoate (0.40 g) in a mixed solvent of acetone (8.00 mL)-acetonitrile (8.00 mL)-water (8.00 mL) were added osmium oxide (fixed catalyst I) (0.15 g) and sodium periodate (1.24 g), and the mixture was stirred overnight at room temperature. The reaction mixture was filtered, and the filtrate was concentrated under reduced pressure. To the residue was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (0.11 g).
