PROCEDURE

实验过程

1 g (3R,5S)-5-biphenyl-4-ylmethyl-3-methylpyrrolidin-2-one (2-a, R1=H), 10 ml ethanol and 1.4 g para-toluenesulphonic acid were heated at about 80-120° C. for about 24 hours. The mixture was evaporated to dryness to obtain (2R,4S)-4-amino-5-biphenyl-4-yl-2-methylpentanoic acid ethyl ester (p-toluenesulfonate salt). Spectroscopic data as in Example 12.
