Procedure

The title compound was prepared using a similar procedure as described in Example 1, Step 11, starting from (S)-2-[4-(3-aminopropoxy)-2,6-dichlorobenzoylamino]-3-[4-(2,6-dichlorobenzoylamino)phenyl]propionic acid (107 mg, 0.15 mmol), 3-[2-[2-[2-[2-[2-[2-[2-[[3-(2,5-dioxo-2,5-dihydro-pyrrol-1-yl)-propionylamino]ethoxy]ethoxy]ethoxy]ethoxy]ethoxy]ethoxy]ethoxy]ethoxy]propionic acid-2,5-dioxo-pyrrolidin-1-yl ester (100 mg, 0.145 mmol), and DIPEA (194 mg, 261 uL, 1.5 mmol), and after HPLC purification, resulted in a white solid (50 mg, 28%). ES(+)-HRMS m/e calcd. for C52H65Cl4N5O17 (M+Na)+ 1194.3022, obsd. 1194.3028.
