Procedure
A mixture of 2-(cyclopentylamino)-N-(4-ethoxycarbonylbenzyl)-5-nitrobenzamide (645 mg), ethanol (30 mL) and 1N-sodium hydroxide solution (5 mL) was heated for 2 hours under reflux. The mixture was acidified with 1 N-hydrochloric acid to pH 4 and the organic solvent was removed by evaporation. The resulting precipitates were collected by filtration and washed with water and diethyl ether to give N-(4-carboxybenzyl)-2-(cyclopentylamino)-5-nitrobenzamide as yellow powders (541 mg).
