실험 절차

To a mixture of 1-(2,2-difluoro-1,3-benzodioxol-4-yl)-5-methoxy-4-oxo-1,4-dihydropyridazine-3-carboxylic acid (3.8 g, 12 mmol), HOBt (2.7 g, 17 mmol) and WSC (3.4 g, 17 mmol) in DMF (50 mL) was added N,O-dimethylhydroxylamine hydrochloride (2.3 g, 23 mmol) and Et3N(4.9 mL, 35 mmol), and the mixture was stirred at room temperature overnight. The mixture was diluted with water (200 mL) and extracted with AcOEt (250 mL×2). The combined organic layer was washed with saturated NaHCO3 aqueous solution and brine, dried over MgSO4, filtered and concentrated under reduced pressure to give orange crystals. The crystals were washed with AcOEt/hexane (1/4) to give the title compound (2.7 g, 62% yield) as pale yellow crystals: 1H NMR (300 MHz, CDCl3): δ ppm 3.41 (3H, s), 3.71 (3H, s), 3.96 (3H, s), 7.12 (1H, dd, J=7.9, 1.1 Hz), 7.23 (1H, d, J=8.7 Hz), 7.57 (1H, dd, J=8.7, 1.1 Hz), 8.06 (1H, s).
