Reaction Steps

The title compound (24 mg) was prepared from (S)-2-tert-butoxycarbonylamino-3-{(S)-2-[4-(3,4-dichloro-benzyloxy)-phenyl]-2,3-dihydro-benzo[1,4]dioxin-6-yl}-propionic acid methyl ester, which was deprotected according to General Procedure C, subjected to General Procedure V, then acylated with benzoyl chloride according to General Procedure F. Hydrolysis followed General Procedure B and the resulting acid and (S)-2-amino-3-[4-(2-methyl-pyridin-4-yloxy)-phenyl]-propionic acid methyl ester dihydrochloride were reacted according to General Procedures L and B. LCMS (m/z): 845.
