実験手順

Under a nitrogen atmosphere, 100 mg (0.178 mmol) of 1-[2(S)-hydroxy-3(S)-(N-(quinoline-2-carbonyl)-(L)-asparaginyl)amino-4-phenyl-butyl]-1-[cyclohexylmethyl]hydrazine (Example 71e) i)) and 34 mg (0.196 mmol) of N-methoxycarbonyl-(L)-valine (Example 73b) are dissolved in 1.75 ml of a 0.3M solution of NMM in DMF, 74 mg (0.196 mmol) of HBTU are added and the mixture is stirred at RT. Since, after 3 days, there is still unreacted hydrazine present, a further 0.3 equivalents in each case of N-methoxycarbonyl-(L)-valine and HBTU in 0.48 ml of 0.3M NMM/DMF is added. After 18 h the reaction mixture is concentrated by evaporation under HV, the residue is dissolved in methylene chloride and washed with saturated NaHCO3 solution, water and brine, the aqueous phases are extracted twice with methylene chloride, and the organic phases are dried with Na2SO4 and concentrated by evaporation. Column chromatography (SiO2, methylene chloride/methanol 15:1) and digestion from DIPE yields the title compound: TLC Rf (A')=0.17; tRet (V)=14.6 min; FAB-MS (M+H)+ =718.
