実験手順

A procedure similar to that described in Example 1 was repeated, except that (2S,3S)-3-(N2 -benzyloxycarbonyl-L-asparaginyl)amino-2-hydroxy-4-phenylbutyric acid (prepared as described in Preparation 1) and 1-t-butoxycarbonyl-N-t-butyl-4-oxo-L-prolinamide (prepared as described in Preparation 3) were used as starting materials, in relative proportions similar to those used in that Example, to obtain the title compound as colorless powdery crystals, melting at 116°-120° C.
