Reaction Steps

A mixture of 8-bromo-6-chloroimidazo[1,2-b]pyridazine (272 mg, 1.17 mmol, Eq: 1.00) and (6-aminopyridin-3-yl)(morpholino)methanone (255 mg, 1.23 mmol, Eq: 1.05) in DMF (10.0 ml) was cooled to 0° C. To this reaction mixture was added sodium hydride (150 mg, (60% in mineral oil), 3.74 mmol, Eq: 3.2). The reaction was allowed to stir at 0° C. for 10 minutes and then allowed to warm to room temperature and stir 18 h. The reaction mixture was quenched with sat. NaHCO3 (aq) and diluted with water and EtOAc. An insoluble solid was collected by filtration to give [6-(6-chloro-imidazo[1,2-b]pyridazin-8-ylamino)-pyridin-3-yl]-morpholin-4-yl-methanone (420 mg, 99%). LC/MS-ESI observed [M+H]+ 358.
