Ethanol → trans-N-{[2-(2-methylpyrazolo[1,5-a]pyridin-4-yl)cyclopropyl]methyl}cyclopropanecarboxamide

Participants

Reaction Steps

To a suspension of 1-[(1R,2R)-2-(2-methylpyrazolo[1,5-a]pyridin-4-yl)cyclopropyl]methanamine dihydrochloride (750 mg, 2.74 mmol) and triethylamine (1.52 mL, 10.9 mmol) in tetrahydrofuran (27 mL) was added cyclopropanecarbonyl chloride (372 μL, 4.10 mmol) under ice-cooling, and the mixture was stirred at room temperature for 3 hr. Ethanol was added to the reaction 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) to give the title compound (647 mg, yield 88%).
