反応手順
(S)-2-({(3S,8S)-3-[4-(3,4-Dichloro-benzyloxy)-phenyl]-2,3,6,7,8,9-hexahydro-[1,4]dioxino[2,3-g]isoquinoline-8-carbonyl}-amino)-3-[4-(2,3-dimethyl-pyridin-4-yloxy)-phenyl]-propionic acid methyl ester bis hydrochloride (25 mg) was reacted with isopropyl chloroformate according to General Procedure G (with excess of chloroformate). The resulting compound was hydrolyzed according to General Procedure B to give the title compound (4 mg). LCMS (m/z): 841.
