Reaction Steps

To a solution of ethyl 4,6-dichloropyridazine-3-carboxylate (1.63 g, 7.36 mmol) in acetonitrile (25 mL) was added 6-isopropoxypyridin-2-amine (1.12 g, 7.36 mmol) and the mixture heated at 130° C. in a sealed tube for 60 h. Upon completion, the mixture was concentrated on to silica gel and purified by chromatography (20% to 66% EtOAc in hexanes) to give ethyl 6-chloro-4-(6-isopropoxypyridin-2-ylamino)pyridazine-3-carboxylate (330 mg, 13%). MS (EI/CI) m/z: 337.1 [M+H].
