Versuchsvorschrift

To a solution of (S)-2-[[1-(2-aminoethyl)cyclopentanecarbonyl]amino]3-[4-(2,6-dichlorobenzoylamino)phenyl]propionic acid (191.5 mg, 0.39 mmol) and 3-[2-[2-[2-[[3-(2,5-dioxo-2,5-dihydro-pyrrol-1-yl)-propionylamino]-ethoxy]ethoxy]ethoxy]ethoxy]propionic acid-2,5-dioxo-pyrrolidin-1-yl ester (200 mg, 0.39 mmol) in DMSO (2 mL) was added an excess of DIPEA (151 mg, 203 uL, 1.17 mmol) at room temperature under nitrogen atmosphere. The resulting light yellow solution was stirred for 1 h at which time LCMS analysis indicated the absence of starting material. Then, the excess DIPEA was removed under vacuum and the desired product was isolated by purification using an HPLC method to obtain 90 mg (26% yield) of (S)-3-[4-(2,6-dichlorobenzoylamino)phenyl]-2-[[1-[2-[3-[2-[2-[2-[2-[3-(2,5-dioxo-2,5-dihydropyrrol-1-yl)propionylamino]ethoxy]ethoxy]ethoxy]ethoxy]propionylamino]ethyl]cyclopentanecarbonyl]amino]propionic acid as a white solid. ES(+)-HRMS m/e calcd. for C42H53Cl2N5O12 (M+H)+ 890.3141, obsd. 890.3140.
