실험 절차

(S)-2-({(3S,8S)-3-[4-(3,4-Dichloro-benzyloxy)-phenyl]-2,3,6,7,8,9-hexa hydro-[1,4]dioxino[2,3-g]isoquinoline-8-carbonyl}-amino)-3-[4-(2,3-dimethyl-pyridin-4-yl)-phenyl]-propionic acid methyl ester bis hydrochloride (25 mg) was dissolved in 1:1 EtOAc and saturated aqueous NaHCO3 and 3,5-dimethyl-isoxazole-4-carbonyl chloride (3 eq.) were added. After stirring at room temperature for 1 hour, the layers were separated and the organic layer was dried over Na2SO4 and evaporated. The residue was purified by over silica (hexanes to 8:2 hexanes-EtOAc to 6:4 hexanes-EtOAc to 6:4 hexanes-EtOAc+2% MeOH to DCM+3% MeOH). The resulting compound was hydrolyzed according to General Procedure B to give the title compound (16 mg). LCMS (m/z): 862.
