PROCEDURE

实验过程

0.5 g (3R,5S)-5-biphenyl-4-ylmethyl-1-(2,2-dimethylpropionyl)-3-methylpyrrolidin-2-one, 5 ml ethanol and 1.1 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-toluenesulphonate salt). 1H NMR (CDCl3): 1.08 (3H), 1.16 (3H), 1.87 (1H), 1.95 (1H), 2.38 (3H), 2.77 (1H), 2.92 (1H), 3.15 (1H), 3.69 (1H), 4.07 (2H), 7.16-7.77 (13H), 9.89 (3H).
