Procedure

A mixture of 1-(2,3-difluoro-4-morpholin-4-ylphenyl)-5-methoxy-4-oxo-1,4-dihydropyridazine-3-carboxylic acid (3.8 g, 10 mmol), N,O-dimethylhydroxylamine hydrochloride (1.1 g, 11 mmol), HOBt (1.5 g, 11 mmol), triethylamine (2.9 mL, 21 mmol) and WSC (2.2 g, 11 mmol) in DMF (20 mL) was stirred at room temperature overnight. The mixture was diluted with AcOEt, washed with water and brine, dried over MgSO4 and concentrated under reduced pressure to give the title compound (3.3 g, 77% yield) as a brown solid: NMR (300 MHz, DMSO-d6): δ ppm 3.05-3.18 (4H, m), 3.24 (3H, s), 3.57 (3H, s), 3.68-4.02 (7H, m), 7.03 (1H, td, J=8.8, 2.1 Hz), 7.27-7.81 (1H, m), 8.50 (1H, s).
