PROCEDURE
实验过程
A solution of (S)-di-tert-butyl 2-(3-((S)-1-tert-butoxy-6-(8-(2,5-dioxopyrrolidin-1-yloxy)-8-oxooctanamido)-1-oxohexan-2-yl)ureido)pentanedioate (0.356 g, 0.48 mmol), the compound of Compound 13 (0.16 g, 0.48 mmol) and DIPEA (1.0 mL) in DMF (5.0 mL) was stirred at room temperature for overnight. The solvent was evaporated to give a residue, which was purified by Biotage eluting with DCM/MeOH to give (7S,11S,26S)-26-(4-(bis((1-methyl-1H-imidazol-2-yl)methyl)amino)butyl)-7,11-bis(tert-butoxycarbonyl)-2,2-dimethyl-4,9,17,24-tetraoxo-3-oxa-8,10,16,25-tetraazaheptacosan-27-oic acid (81 mg, 18%). MS (ESI), 481 (M/2+H)+.
