Reaction Steps

Triethylamine (20 mL), tert-butyl alcohol (30 mL) and diphenylphospholylazide (1.95 mL, 9.05 mmol) were added to a solution of the resulting 8-(2,4-dimethylphenyl)-2-ethyl-6-methylimidazo[1,2-b]pyridazine-3-carboxylic acid (2.8 g, 9.05 mmol) in toluene (40 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 tert-butyl N-[8-(2,4-dimethylphenyl)-2-ethyl-6-methylimidazo[1,2-b]pyridazin-3-yl]carbamate as a crude compound.
