Reaction Steps

To a solution of 4-[5-(1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-1,2,4-triazol-3-yl)-4-vinyl-1,3-thiazol-2-yl]pyridine (1.43 g, 2.60 mmol) in a 3:1 mixture of 1,4-dioxane (17.5 mL, 224.6 mmol) and water (5.8 mL, 324.25 mmol) was added 2,6-lutidine (1.50 mL, 12.98 mmol) and the mixture was cooled to 0° C. Sodium metaperiodate (2.80 g, 12.98 mmol) was added followed by the addition of 4% osmium tetroxide in water (0.50 mL, 0.080 mmol) and the reaction mixture was slowly warmed to ambient temperature and allowed to stir overnight. Water (10 mL) was added. The resulting yellow precipitate was collected by filtration, washed with water, ether and MeOH. The filtrate was concentrated under reduced pressure and dried on the high vac to give the title compound (1.0 g, yield 99%). LCMS: (FA) ES+, 388. 1H NMR (400 MHz, d6-DMSO) δ: 10.70 (s, 1H), δ:9.05 (s, 1H), 8.79-8.80 (dd, J=1.5 Hz, 2H), 7.98-8.0 (dd, J=1.5 Hz, J=1.7 Hz, 2H), 5.64-5.66 (s, br, 2H), 3.64-3.68 (m, 2H), 0.870-0.90 (m, 2H), −0.03 (s, 9H).
