2-(2,2-diethoxyethyl)isoindoline-1,3-dione (40.00 g, 0.15 mol) was dissolved in 85% formic acid (150 mL) and the mixture was stirred for 2 h at rt. After tlc analysis indicated full conversion to the aldehyde (2,4-DNP stain used for visualization), the solvent was removed and the resultant solid was dried at 150 mm torr vacuum to give 2-(1,3-dioxoisoindolin-2-yl)acetaldehyde (27 g, 95%).
