실험 절차

Methyl (4-{3-cyano-4-(1,2-dihydroxyethyl)-5-[1-(tetrahydro-2H-pyran-2-yl)-1H-1,2,4-triazol-3-yl]-2-thienyl}pyridin-2-yl)carbamate (0.362 g, 0.769 mmol) was dissolved in acetone (40 mL) and water (10 mL). Sodium metaperiodate (0.494 g, 2.31 mmol) was added and the mixture was stirred at room temperature for 6 hours. Sodium metaperiodate (0.329 g, 1.54 mmol) was added and the mixture was stirred for 16 more hours. The mixture was concentrated in rotavapor. The residue was triturated with water, filtered and washed thoroughly with water, then dried in lyophilizer to give a dry solid product (0.320 g, yield 94.8%). LC/MS: (FA) ES+ 439. 1H NMR (400 MHz, d6-dmso) δ 10.67 (s, 1H), 10.57 (s, 1H), 9.05 (s, 1H), 8.49 (m, 1H), 8.28 (s, 1H), 7.50 (m, 1H), 5.69-5.73 (m, 1H), 3.94-3.98 (m, 1H), 3.73 (s, 3H), 3.66-3.71 (m, 1H), 1.93-2.12 (m, 3H), 1.58-1.71 (m, 3H).
