Procedure

With the exclusion of air, 270 mg (1.43 mmol) of N-methoxycarbonyl-(L)-iso-leucine, 513 mg (2.67 mmol) of EDC and 241 mg (1.78 mmol) of HOBT are dissolved in 7.8 ml of DMF. After stirring for 15 min, 0.75 ml (5.4 mmol) of TEA and 510 mg (0.89 mmol) of 1-{4-[2-(1-methyl -1-phenyl-ethyl)-2H-tetrazol-5-yl]-phenyl}-4(S)-hydroxy-2-(tert-butoxycarbonyl)amino-5(S)-amino-6-phenyl-2-azahexane (Example 25f) in 3.7 ml of DMF are added. After 20 hours, the mixture is worked up analogously to Example 25g to yield the title compound: HPLC20-100 : tRet =18.5; FAB MS (M+H)+ =743.
