실험 절차

2-(1-isopropyl-3-methyl-1H-1,2,4-triazol-5-yl)-9-vinyl-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine (0.300 g, 0.000894 mol) was dissolved in THF (20 mL) and H20 (10 mL). Osmium tetroxide (0.550 mL, 0.0716 mmol, 4% wt in water) was added followed by Sodium metaperiodate (0.383 g, 0.00179 mol). The reaction was stirred overnight at room temperature. The reaction was quenched using saturated sodium thiosulfate. 2-(1-isopropyl-3-methyl-1H-1,2,4-triazol-5-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-9-carbaldehyde (0.302 g, 95.1% yield) was isolated using an aqueous workup and carried on without further purification
