Procedure

3-Aminophenylacetic acid was prepared from a solution of 3-nitrophenylacetic acid (5.08 g, 28 mmol) in absolute ethanol (100 ml) which was hydrogenated at 40° C. and 40 psi in the presence of 5% Pd/C catalyst for 3 hours. The catalyst was removed by filtration, and upon removal of the solvent in vacuo, a highly viscous yellow oil remained which resisted crystallization.
