Versuchsvorschrift
Intermediate XXII is prepared based on the synthetic approach shown in Scheme 2. N1-(2-aminoethyl)-3-(4-nitrophenyl)propane-1,2-diamine (XX) is protected using tosyl chloride and triethylamine to afford tritosylated compound 4-methyl-N-(2-(4-methylphenylsulfonamido)-3-(4-nitrophenyl)propyl)-N-(2-(4-methylphenylsulfonamido)ethyl)benzenesulfonamide (XXI). Deprotonation of (XXI) with sodium ethoxide in ethanol produces a disodium salt of compound (XXI), compound (XXII). Compound (XX) is produced according to the method of Corson et al. (Corson, D. T.; Meares, C. F. Bioconjugate Chem. 2000, 11, 292-299, the disclosure of which is incorporated herein by reference).
