Reaction Conditions:
with hydrogenchloride in 1,4-dioxane;water at 20; for 0.583333 h;
Steps:
40 Example 40. (S)-2-((2R,3R)-3-((S)- 1 -((3R,4S ,5S)-4-((S)-N,3-dimethyl-2-((S)-3- methyl-2-(methylamino)butanamido)butanamido)-3 -methoxy-5-methylheptanoyl)-pyrrolidin-2-yl)-3 -methoxy-2-methylpropanamido)-3 -phenylpropanoic acid (101)
(S)-2-((2R,3R)-3-((S)- 1 -((6S ,9S, 12S, 1 3R)- 12-((S)-sec-butyl)-6,9-diisopropyl- 13- methoxy-2,2,5,11 -tetramethyl-4,7, 1 0-trioxo-3 -oxa-5 ,8,11 -triazapenta-decan- 15- oyl)pyrrolidin-2-yl)-3 -methoxy-2-methylpropanamido)-3 -phenylpropanoic acid (25 mg,0.030 mmol) in the mixture of HC1 (conc. 0.3 ml) and 1,4-dioxane (0.9 ml) was stirred at RT for 35 mm. The mixture was diluted with EtOH (1.0 ml) and toluene (1.0 ml), concentrated and re-evaporated with EtOH/toluene (2:1) to afford the title compound as a white solid (22 mg, -400% yield) for the next step without further purification. LC-MS (ESI) mlz calcd. for C39H66N508 [M+Hj: 732.48, found: 732.60.
