Participants

Reaction Steps

To a solution of 3-(2,3-dihydrofuro[3,2-c]pyridin-4-yl)propanamide (435 mg, 2.26 mmol) in dichloromethane (10 mL) were added pyridine (384 μL, 4.75 mmol) and trifluoroacetic anhydride (384 μL, 2.72 mmol), and the mixture was stirred at room temperature for 13 min. The reaction solution was diluted with saturated aqueous sodium hydrogen carbonate solution, and the mixture was extracted with dichloromethane. The extract was dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (NH, ethyl acetate/hexane=30/70→70/30) to give the title compound (132 mg, yield 33%).
