Reaction Steps
Xylene (15 ml) was added to 4-methylphthalic anhydride (3.0 g) and urea (1.2 g), and the mixture was stirred overnight at 150° C. The reaction mixture was cooled to room temperature, and precipitated crystals were collected by filtration and washed with ethanol and water. The crystals were dried under reduced pressure to give 4-methylphthalimide (2.4 g, Y.:82%) as white crystals.
