Reaction Steps

A mixture of N-(1-acetyl-2,3-dihydro-1H-pyrrolo[2,3-b]pyridin-4-ylmethyl)-acetamide (0.50 g), HCl (conc., 3 mL) and EtOH (12 mL) was heated to 70° C. for overnight. Additional 3 mL of conc. HCl was added to the reaction and the heating was continued for 3 more days. Solvent was evaporated to give a white residue as crude C-(2,3-dihydro-1H-pyrrolo[2,3-b]pyridin-4-yl)-methylamine HCl salt, which was used without further purification.
