To mixture of 6-chloro-3-(2-fluoro-4-iodo-phenylamino)-pyridazine-4-carboxylic acid (34 mg, 0.09 mmol) in DMF was added morpholine (37.7 mg, 0.43 mmol). The mixture was heated at 135° C. for 3.5 h. The mixture was diluted with ether and extracted with NaOH (1N). The aqueous layer was acidified by concentrated HCl. The desired product was precipitated and was collected by vacuum filtration. LC/MS [5.51 min; 445 (M+1)].
