Procedure

14 g Ethyl(o-nitro-benzyloxy)acetate were dissolved in 300 ml 96% ethanol and 1.5 g 5% Pd on carbon was added. The mixture was then hydrogenated at normal pressure and room temperature. After completion of the reaction the mixture was filtered and the filtrate was added to 50 ml 4N NaOH and the resulting solution was left at room temperature for 2 hours, whereafter 50 ml 4N HCl were added. The mixture was evaporated, and the residue was stirred with 200 ml acetone. The mixture was filtered. The filtrate was evaporated to give o-amino-benzyloxy acetic acid as an oil.
