Reaction Steps

To a solution of ethyl 4,6-dichloropyridazine-3-carboxylate (1.47 g, 6.64 mmol) in acetonitrile (7.6 mL) was added 5-isopropyl-6-methoxypyridin-2-amine (830 mg, 4.99 mmol) and the mixture heated at 100° C. in a sealed tube for 18 h. Upon completion, the mixture was concentrated onto silica gel and purified by chromatography (silica, 10% to 80% ethyl acetate in hexanes) to give ethyl 6-chloro-4-(5-isopropyl-6-methoxypyridin-2-ylamino)pyridazine-3-carboxylate (500 mg, 28.5%). MS (EI/CI) m/z: 351.2 [M+H].
