실험 절차

Prepared, analogously to Example 13a) but using dichloromethane as solvent instead of tetrahydrofuran and without using triethylamine, from 4-[[[(2,2-diphenylethyl)amino]carbonyl]amino]benzenemethylamine (mp.: 161°-163° C.; obtained from 4-cyanophenylisocyanate and 2,2-diphenylethylamine via N-(4-cyanophenyl-N'-(2,2-diphenylethyl)-urea, mp.: 235°-237° C., and finally by catalytic hydrogenation in the presence of Raney nickel and ammonia), (R)-N5 -[amino(nitroimino)methyl]-N2 -(diphenylacetyl)-ornithine, DCC and HOBt in a yield of 48% of theory.
