Procedure

Ten percent Pd/C (0.1003 g) was added to a solution of N-t -butyl-4-nitrobenzamide (0.7349 g, 3.31 mmol) in ethyl acetate (10 ml), and stirred under a hydrogen atmosphere for 1 hour. The reaction mixture was filtered through Celite® bed and the solvent was evaporated. The residue was purified by silica gel chromatography (hexane/ethyl acetate/triethylamine=50/100/1) to give the title compound (0.6156 g; 97%).
