Procedure

In the same manner as in Example 18-4 and using 5-methyl-2-(trifluoromethyl)-3-furoic acid (175 mg, 0.904 mmol), tetrahydrofuran (8 mL), oxalyl chloride (118 μL, 1.36 mmol), N-[6-(3-aminophenoxy)[1,2,4]triazolo[1,5-a]pyridin-2-yl]cyclopropanecarboxamide (70.0 mg, 0.226 mmol), N,N-dimethylformamide (1 drop) and N,N-dimethylacetamide (3 mL) as starting materials, the title compound (72.0 mg, 66%) was obtained as a white solid.
