To a solution of trans-1-[2-(2-methylpyrazolo[1,5-a]pyridin-4-yl)cyclopropyl]methanamine (50.0 mg, 0.248 mmol) and triethylamine (41.6 μL, 0.298 mmol) in tetrahydrofuran (2.5 mL) was added benzoyl chloride (31.7 μL, 0.273 mmol) under ice-cooling, and the mixture was stirred under ice-cooling for 5 min. The reaction solution was diluted with saturated aqueous sodium hydrogen carbonate solution. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (methanol/ethyl acetate=0/100→5/95) 15 and silica gel column chromatography (NH, methanol/ethyl acetate=0/100→5/95) to give the title compound (51.0 mg, yield 67%).
