Procedure

With the exclusion of air, 261 mg (1.38 mmol) of N-methoxycarbonyl-(L)-iso-leucine, 496 mg (2.58 mmol) of EDC and 232 mg (1.72 mmol) of HOBT are dissolved in 7.5 ml of DMF. After 15 min, 0.72 ml (5.17 mmol) of TEA and 585 mg (0.86 mmol) of 1-{4-[2-(1-methyl-1-phenyl-ethyl)-2H-tetrazol-5-yl]-phenyl}-4(S)-hydroxy-2-amino-5(S)-N-(N-methoxycarbonyl-(L)-tert-leucyl)amino-6-phenyl-2-azahexane hydrochloride (Example 25h) in 3.5 ml of DMF are added. After 20 hours, the mixture is worked up as described under Example 25i. Precipitation with DIPE from a concentrated solution in methylene chloride yields the title compound: HPLC20-100 : tRet =17.5; FAB MS (M+H)+ =814.
