A mixture of 1-formyl-4-oxo-2,4,6,7-tetrahydro-pyrrolo[3,4-c]pyridine-5-carboxylic acid tert-butyl ester (1.2 g, 4.54 mmol) in 50% of trifluoroacetic acid in dichloromethane was stirred at room temperature for 30 minutes. The reaction was concentrated and the residue was recrystallized from dichloromethane to give 400 mg (75%) of 4-oxo-4,5,6,7-tetrahydro-2H-pyrrolo[3,4-c]pyridine-1-carbaldehyde.
