Reaction Steps

S-Benzyl (9S,12S,18S,21S,24S,27S,30S)-30-(((S)-1-(((S)-1-((2-amino-2-oxoethyl)amino)-3-(tert-butoxy)-1-oxopropan-2-yl)amino)-1-oxopropan-2-yl)(methyl)carbamoyl)-12,27-dibenzyl-18-isobutyl-24-isopropyl-2,2,9,11,17,21-hexamethyl-4,7,10,13,16,19,22,25,28-nonaoxo-3-oxa-5,8,11,14,17,20,23,26,29-nonaazadotriacontane-32-thioate (Compound P-146) (11.8 mg, 0.0083 mmol) was dissolved in dichloromethane (150 μL), TFA (75.0 μL, 0.973 mmol) was added and the mixture was stirred at room temperature for 1.5 hours. The reaction solution was concentrated under reduced pressure, and the resulting residue was purified by column chromatography (0.1% aqueous FA solution: 0.1% FA-acetonitrile solution) to afford the title compound (7.3 mg, 69.5%).
