実験手順

To a solution of N-{4-[(Z)-2-(dimethylamino)ethenyl]-5-nitropyridin-2-yl}acetamide (0.7 g, 3 mmol, Step b) in methanol and dichloromethane (5:1, 120 mL), palladium on carbon (0.4 g) was added followed by addition of acetic acid (7 mL). The reaction mixture was then purged with hydrogen gas and stirred overnight at room temperature. The resulting mixture was filtered over celite bed, and the residue was washed with methanol (100 mL). The combined filtrate was concentrated under vacuum and purified by silica gel column chromatography using methanol in dichloromethane (2%) to afford N-(1H-pyrrolo[2,3-c]pyridin-5-yl)acetamide (0.35 g, 71%).
