Reaction Steps

4-Fluorobenzylamine (20 g, 160 mmol) in 10 mL CH2Cl2 was added to phthalic anhydride (5 g, 34 mmol) in 20 mL glacial acetic acid. The reaction was stirred at 100° C. for 4 h as water was collected with a Dean-Stark trap. Solvent was evaporated and the product was obtained by crystallization from ethanol (7.5 g, 87%).
