PROCEDURE
实验过程
19-((S)-1-tert-Butoxycarbonyl-3-{2-[2-({2-[2-(2,5-dioxopyrrolidin-1-yloxycarbonylmethoxy)ethoxy]ethylcarbamoyl}methoxy)ethoxy]ethylcarbamoyl}propylcarbamoyl)nonadecanoic acid tert-butyl ester (3.4 g) was stirred in TFA (75 ml) for 45 min and then concentrated in vacuo. The residue was concentrated with toluene 3 times to give a solid. The residue was crystallised in 2-propanol and filtered to give a white crystalline compound. Yield 80% (2.4 g). LC-MS (electrospray): m/z: 859.44.
