Reaction Steps
Methyl 2-chloro-3-oxopentanoate (7 mL) was added to a solution of the resulting 4-(2,4-dimethylphenyl)-6-methyl-3-pyridazinamine in N,N-dimethylformamide (60 mL), and the mixture was heated at 140° C. for 6 hours. Water was added thereto, which was extracted with ethyl acetate. The organic layer was washed with an aqueous saturated sodium bicarbonate solution and brine, dried over anhydrous magnesium sulfate and evaporated, to give 8-(2,4-dimethylphenyl)-2-ethyl-6-methylimidazo[1,2-b]pyridazine-3-carboxylic acid methyl ester as a crude product.
