実験手順

In acetic acid (100 ml) was dissolved N-(4-nitrobenzyl)sarcosine methyl ester (5.96 g), and to the mixture was added little by little reduced iron (7 g). The mixture was stirred at room temperature overnight. The solvent was evaporated, and to the residue was added ethyl acetate. The precipitates were filtered off, and the filtrate was washed with sodium hydroxide solution, water and saturated brine, and dried with anhydrous magnesium sulfate. Under reduced pressure, the solvent was evaporated, and the resulting residue was purified with silica gel column chromatography (ethyl acetate/hexane) to give N-(4-aminobenzyl)sarcosine methyl ester (3.0 g) as red oil.
