실험 절차

11 g of hydroxylamine hydrochloride is added to a suspension of 30 g of 5-oxo-5H-[1]benzopyrano[2,3-b]pyridine-7-carbaldehyde in 600 ml of pyridine, and the mixture is vigorously stirred at 80°C for 1 hour. After cooling, the crystals are filtered off, washed with water, and dried to give crude 5-oxo-5H-[1]benzopyrano[2,3-b]pyridine-7-carbaldehyde oxime melting at 254°-256°C with decomposition.
