実験手順
Analogously to Example 46, 0.96 g (1.5 mmol) of 1-[4-(pyridin-2-yl)-phenyl]-4(S)-hydroxy-2-amino-5(S)-N-(N-methoxycarbonyl-(L)-iso-leucyl)amino-6-phenyl-2-azahexane 3HCl (Example 47d) in 10 ml of DMF are reacted with 0.263 g (1.5 mmol) of N-methoxycarbonyl-(L)-valine, 0.446 g (1.5 mmol) of TPTU and 0.78 ml (4.5 mmol) of DBU in 7 ml of DMF. After working up, the title compound is obtained: TLC: Rf=0.4 (ethyl acetate); HPLC20-100: tRet=11.23. FAB MS (M+H)+=691.
