Procedure

D-Histidine hydroxamic acid (1.9 g, 11.2 mMol) was dissolved in dimethylformamide (75 ml) and water (100 ml). Phthalic anhydride (1.65 g, 11.2 mMol) was added, the solution stirred 4 hours, evaporated to an oil which was crystallized from water/ethanol, and crystallized again from water to yield 1.6 g, m.p. 175° (dec.) of N-(2-carboxybenzoyl)-D-histidine hydroxamic acid.
