Participants

Reaction Steps

In the same manner as in Example 259 and using 3-chloro-1-methyl-1H-pyrazole-5-carboxylic acid (59 mg, 0.37 mmol), tetrahydrofuran (5 mL), N,N-dimethylformamide (1 drop), oxalyl chloride (130 μL, 1.5 mmol), N-[6-(3-amino-4-fluorophenoxy)imidazo[1,2-b]pyridazin-2-yl]cyclopropanecarboxamide (100 mg, 0.31 mmol) and N,N-dimethylacetamide (5 mL) as starting materials, the title compound (100 mg, 71%) was obtained as a white solid.
