To a solution of imidazo[1,2-a]pyridine-6-carboxylic acid (87 mg, 0.54 mmol) and C-(5-(3-fluorophenoxy)thiophen-2-yl)methylamine (120 mg, 0.54 mmol) in N,N-dimethylformamide (5 mL) were added benzotriazol-1-yl-tris(dimethylamino)phosphonium hexafluorophosphate (240 mg, 0.54 mmol) and triethylamine(0.15 mL, 1.08 mmol), and the solution was stirred for 40 minutes at 80° C. Water and ethyl acetate were added to the reaction mixture for extraction, and the organic layer was washed twice with water. Silica gel was added to the organic layer, solvent was evaporated in vacuo for adsorption, purification was carried out by silica gel column chromatography (hexane:ethyl acetate=1:1, then ethyl acetate), and the title compound (90 mg, 0.25 mmol, 45.4%) was obtained as a light brown oil.
