Versuchsvorschrift
A mixture of 3-chlorophthalic acid anhydride (9 g, 49.2 mmol) and formamide (100 mL) was heated to 125° C. and stirred for 3 h. Water (300 mL) was then added and the mixture was cooled to room temperature. The mixture was filtered and the resulting white solid was washed with water and dried to give 4-chloro-1H-isoindole-1,3(2H)-dione (7.7 g, 86% yield).
