Participants

Reaction Steps

Using N-[6-(3-amino-4-methylphenoxy)imidazo[1,2-b]pyridazin-2-yl]cyclopropanecarboxamide (323 mg, 1.0 mmol), 1,4-dimethyl-1H-pyrazole-3-carboxylic acid (154 mg, 1.1 mmol) tetrahydrofuran (2.0 mL), N,N-dimethylformamide (1 drop), thionyl chloride (0.08 mL, 1.1 mmol) and N,N-dimethylacetamide (6.0 mL), and by a reaction in the same manner as in Example 203, the title compound (208 mg, 47%) was obtained as pale-yellow crystals.
