Reaction Steps

To a stirred solution of 3,3-dibromo-2-oxo-2,3-dihydro-1H-pyrrolo[2,3-b]pyridine-4-carbonitrile (4 g) in CH3CN (75 mL) was added AcOH (2 mL) followed by Zinc dust (4, 63 mmol). Mixture was stirred for 2 h at RT and was filtered. Solvent was evaporated and MeOH was added. A solid precipitated, which was filtered and dried.
