A mixture of (4-amino-phenyl)-acetic acid (25 g) in acetic acid (200 mL) was treated with acetic anhydride (31.3 mL). The mixture was heated on a steam bath for 4 hours, then cooled, then treated with water (20 mL) and then evaporated. The residue was dried under vacuum to give the title compound (30.4 g) as a beige coloured solid.
