Reaction Steps
A solution of 4-nitrophthalic anhydride (9.66 g, 50 mmol) and glycine (3.75 g, 50 mmol) in N,N-dimethylformamide was stirred for 30 minutes at 140° C. The reaction mixture was poured into water (150 mL). Resulting precipitate was collected by filtration and washed with water, which was collected by filtration and washed with water, which was recrystallized from ethanol to give 9.69 g (yield 77%) of the titled compound, m.p. 195.5°-196.5° C. (ethanol).
