Procedure
Analogously to Example 1, a solution of 0.315 g (0.5 mmol) of 1-[4-(pyridin-2-yl)-phenyl]-4(S)-hydroxy-2-amino-5(S)-N-(N-methoxycarbonyl-(L)-valyl)amino-6-phenyl-2-azahexane hydrochloride in 3 ml of DMF is added dropwise to a mixture of 0.152 g (0.8 mmol) of N-methoxycarbonyl-(L)-tert-leucine, 0.287 g (1.5 mmol) of EDC, 0.135 g (1 mmol) of HOBT and 0.49 ml of TEA in 3 ml of DMF. After working up, the crude product is purified by subsequent medium-pressure column chromatography (SiO2 ; hexane/ethyl acetate) to yield the title compound. TLC: Rf =0.35 (ethyl acetate); HPLC20-100 : tRet =11.05. FAB MS (M+H)+ =691.
