PROCEDURE
实验过程
With the exclusion of air, 128 mg (0.67 mmol) of N-methoxycarbonyl-(L)-tert-leucine (Example 2e), 243 mg (1.27 mmol) of EDC and 114 mg. (0.84 mmol) of HOBT are dissolved in 2 ml of DMF. After 15 min, 0.35 ml (2.5mmol) of TEA and 286 mg (0.42 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)-iso-leucyl)amino-6-phenyl-2-azahexane hydrochloride in 1.5 ml of DMF are added. After 20 hours, the mixture is worked up as described under Example 25. Chromatography (SiO2; ethyl acetate/toluene/methylene chloride 2:1:1) yields the title compound: TLC: Rf=0.22 (methylene chloride/ethyl acetate 1:1); HPLC20-100: tRet=17.3; FAB MS (M+H)+=814.
