Procedure

Under an argon atmosphere, 344 mg of 1-[4-(thiazol-5-yl)-phenyl]-4(S)-hydroxy-2-amino-5(S)-N-(N-methoxycarbonyl-(L)-tert-leucyl)amino-6-phenyl-2-azahexane (Example 2d) and 191 μl (1.74 mmol) of NMM in 5.6 ml of DMF are added to 132 mg (0.7 mmol) of N-ethoxycarbonyl-(L)-valine (EP 0 604 368, Example 9a) and 173 mg (0.58 mmol) of TPTU in 2.9 ml of DMF, and the mixture is stirred at room temperature overnight and worked up analogously to Example 3, yielding the title compound: TLC: Rf =0.45 (methylene chloride/THF 4:1); HPLC20-100 : tRet =14.7; FAB MS (M+H)+ =711.
