실험 절차

160 mg (0.23 mmol) of tert-butyl(S)-3-(6-tert-butoxycarbonylaminopyridin-3-yl)-2-[3-((9S,12R)-9-isopropyl-11-oxo-2,7-dioxa-10-azabicyclo[12.2.2]octadeca-1(17),14(18),15-trien-12-yl)ureido]propionate were dissolved in 6 ml of dichloromethane and, after addition of the same volume of TFA, stirred at RT. After 5 h, the mixture was concentrated and purified by preparative HPLC. The required fractions were combined, freed of acetonitrile, mixed with 1N hydrochloric acid, concentrated further and finally freeze dried. 108 mg of the title compound were obtained as hydrochloride.
