Reaction Steps

To tert-Butyl 2-methyl-1-((S)-1-(2-(N-methyl-3-((4-(piperidin-1-yl)-2-(4-(((S)-1,2,3,4-tetrahydronaphthalen-1-yl)carbamoyl)pyridin-2-yl)phenyl)carbamoyl)benzamido) ethyl)pyrrolidin-2-yl)-1-oxo-5,8,11-trioxa-2-azatetradecan-14-oate (16 mg) was added TFA (2 mL). The mixture was stirred at rt for 30 minutes, concentrated and purified by prep. HPLC to give a yellow solid (17.6 mg, 86%). MS (ES, m/z): 946.34 [M+H]+.
