Reaction Steps
Prepared, analogously to Example 67a) but using acetonitrile as solvent instead of dimethylformamide, from (R)-N5 -[amino(nitroimino)methyl]-N2 -(diphenylacetyl)-ornithine, 4-[(methylamino)carbonyl]benzenemethylamine (prepared from 4-cyano-N-methylbenzamide by catalytic hydrogenation in the presence of palladium/animal charcoal) and TBTU in a yield of 22% of theory.
