Procedure
17.5 μl of an aqueous lithium hydroxide solution and 100 μl of water are added to 18 mg of methyl 3-{2-[2-(2-{2-[2-(2-([2-(2,6-bis[(S)-2-eth-(E)-ylidene-7-methoxy-1,2,3,11a-tetrahydropyrrolo[2,1-c][1,4]benzodiazepin-5-one-8-yloxymethyl]pyridin-4-yloxy)ethyl](methyl)amino}-1,1-dimethylethylsulphanyl)acetylamino]ethoxy}ethoxy)ethoxy]ethoxy}propanoate in solution in 270 μl of THF. After 2 h, the mixture is diluted in DCM and a phosphate buffer is added to pH=3. The resulting aqueous phase is extracted 3× with DCM, the combined organic phases are dried over MgSO4 and concentrated under RP and the residue is purified by flash chromatography on silica (Interchrom Puriflash Silica 15/35U 2G) using a gradient from 3 to 15% of methanol in DCM. 11.5 mg of 3-{2-[2-(2-{2-[2-(2-{[2-(2,6-bis[(S)-2-eth-(E)-ylidene-7-methoxy-1,2,3,11a-tetrahydropyrrolo[2,1-c][1,4]benzodiazepin-5-one-8-yloxymethyl]pyridin-4-yloxy)ethyl](methyl)amino}-1,1-dimethylethylsulphanyl)acetylamino]ethoxy}-ethoxy)ethoxy]ethoxy}propanoic acid are thus obtained. LC/MS (D): rt=0.88 min; [M+H2O+Na]+: m/z 1154; [M+H2O+H]+: m/z 1133; [M+H]+: m/z 1115.
