129 mg (0.34 mmol) of HATU and 133 mg (0.95 mmol) of N,N-diisopropylethylamine are added to a solution of 100 mg (0.27 mmol) of N2-[(9H-fluoren-9-ylmethoxy)carbonyl]-L-glutamine and 112 mg (0.35 mmol) of tert-butyl{(4S)-5-amino-4-[(tert-butoxycarbonyl)amino]pentyl}carbamate (Example 86A) in 5 ml of anhydrous DMF at 0° C. The reaction mixture is stirred at RT for 15 h. The solvent is then evaporated and the residue is stirred with water, collected by filtration and dried under high vacuum.
