实验过程

First of all Boc-Arg(NO2)-OH was reacted with thiophene-2-methanamine and TBTU as in Example 8a). The resulting (R)-N5 -[amino(nitroimino)methyl]-N2 -[(tert.-butyloxy)carbonyl]-N-[(2-thienyl)methyl]-ornithinamide was then reacted, without purification, with trifluoroacetic acid as in Example 23b). The crude product obtained in a quantitative yield was further processed without purification.
