N-[3-(1-Methylpiperidin-4-YL)-1H-pyrrolo[3,2-B]pyridin-5-YL]acetamide → 3-(1-Methyl-piperidin-4-yl)-1H-pyrrolo[3,2-b]pyridin-5-ylamine

反応手順

A mixture of 2.5 gm (9.2 mMol) 5-(N-acetylamino)-3-(1-methylpiperidin-4-yl)pyrrolo[3,2-b]pyridine in 40 mL 2N hydrochloric acid was heated at reflux for 1 hour. The reaction mixture was cooled to room temperature, concentrated under reduced pressure, basified (pH~11) with 2N aqueous sodium hydroxide, concentrated under reduced pressure, and extracted well with 3:1 chloroform:isopropanol. The organic extracts were combined, dried over magnesium sulfate and concentrated under reduced pressure to provide 1.98 gm (93%) of the title compound as a brown solid.
