Procedimiento

A mixture of isobenzofuran-1,3-dione (20 g, 135 mmol) and 3-aminopropanoic acid (12 g, 135 mmol) was stirred at 170° C. for 6 h. See FIG. 2. Upon reaction completion, the mixture was diluted with water and extracted with DCM (100 mL×3). The combined organic layers were dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure to give 3-(1,3-dioxoisoindolin-2-yl)propanoic acid 137g (20 g, 69%) as a white solid.
