Participants

Reaction Steps

6-Chloro-3-[(2-fluoro-4-iodophenyl)amino]pyridazine-4-carboxylic acid (144 mg, 0.37 mmol.) and 1,1′-carbonylbis(1H-imidazole) (119 mg, 0.73 mmol) were suspended in N,N-dimethylformamide (1.00 ml). The mixture was stirred over night (12 hr). Solid ammonium acetate (31 mg, 0.40 mmol) then added. The reaction was stirred for another 5 h. Water (0.5 mL) was then added into the mixture. The desired product was precipitated and was collected by vacuum filtration. LC/MS [7.39 min; 393 (M+1)].
