Reaction Steps

A mixture of phthalic anhydride (10 g, 0.067 mmol) and 4-methoxybenzylamine (9.7 ml, 0.074) in glacial acetic acid (60 ml) was stirred in a 90° C. oil bath for 2½ hr, cooled to room temperature and the excess acetic acid removed under reduced pressure. The residual mixture was diluted with water (50 ml) and poured slowly into a saturated NaHCO3 solution (150 ml). The mixture was stirred at room temperature overnight and the precipitate collected by filtration, rinsing further with water. The precipitate was then dried under reduced pressure to provide a white solid product (15.7 g) 87%.
