Procedure

A solution of ethyl 4-(5-tert-butoxycarbonylaminomethyl-2-nitrophenyl)-2-ethoxycarbonylbutanoate (3.2 g, 7.3 mmol) in ethyl acetate (30 mL) was hydrogenated over palladium/charcoal (500 mg) under atmospheric pressure of hydrogen at room temperature for 2.5 h. The mixture was passed through celite and the filtrate was concentrated to give 2.8 g of the title compound (94%).
