Procedure

The process is performed as in Example 2, starting with 7.15 g of ethyl (2S)-2-(acetylamino)-3-(3-nitrophenyl)propanoate and 1.46 g of sodium borohydride in 70 cm3 of ethanol. After an identical work-up, 5.8 g of N-[(1S)-2-hydroxy-1-(3-nitrobenzyl)-ethyl]acetamide are obtained in the form of a white solid melting at 131° C.
