A solution of 14.3 g of N-(2-chloro-6-nitrobenzyl)-L-alanine ethyl ester in 50 ml of absolute ethanol was hydrogenated in the presence of 1 g of Raney nickel. After completion of the hydrogenation, the catalyst was filtered off and the filtrate was evaporated to dryness. There were obtained 12.6 g (99% of theory) of N-(2-amino-6-chlorobenzyl)-L-alanine ethyl ester; nD22 =1.5430.
