Procedure

In the same manner as in Example 18-4 and using 2-methyl-5-(trifluoromethyl)-1,3-oxazole-4-carboxylic acid (238 mg, 1.22 mmol), tetrahydrofuran (7 mL), oxalyl chloride (160 μL, 1.83 mmol), N-[6-(3-amino-4-fluorophenoxy)[1,2,4]triazolo[1,5-a]pyridin-2-yl]cyclopropanecarboxamide (200 mg, 0.611 mmol), N,N-dimethylformamide (1 drop) and N,N-dimethylacetamide (3 mL) as starting materials, the title compound (276 mg, 90%) was obtained as a white solid.
