Tetrahydrofuran → N-[5-({2-[(cyclopropylcarbonyl)amino][1,2,4]triazolo[1,5-a]pyridin-6-yl}oxy)-2-fluorophenyl]-1-ethyl-3-methyl-1H-pyrazole-4-carboxamide

Participants

Reaction Steps

In the same manner as in Example 55 and using 1-ethyl-3-methyl-1H-pyrazole-4-carboxylic acid (62.6 mg, 0.406 mmol), tetrahydrofuran (5 mL), thionyl chloride (70.0 μL, 0.807 mmol), N,N-dimethylformamide (2 drops), N-[6-(3-amino-4-fluorophenoxy)[1,2,4]triazolo[1,5-a]pyridin-2-yl]cyclopropanecarboxamide (120 mg, 0.367 mmol) and N,N-dimethylacetamide (5 mL) as starting materials, the title compound (60.4 mg, 36%) was obtained as a white solid.
