Procedure
(S)-2-({(S)-7-(2-amino-4-methyl-thiazole-5-sulfonyl)-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′-cyano-biphenyl-4-yl)-propionic acid methyl ester (30 mg) was reacted with isobutyryl chloride according to General Procedure F to give (S)-3-(4′-cyano-biphenyl-4-yl)-2-({(S)-7-[2-(isobutyryl-amino)-4-methyl-thiazole-5-sulfonyl]-3-[4-(3,4-dichloro-benzyloxy)-phenyl]-2,3,6,7,8,9-hexahydro-[1,4]dioxino[2,3-g]isoquinoline-8-carbonyl}-amino)-propionic acid methyl ester. This ester, upon hydrolysis according to General Procedure B, gave the title compound. LCMS (m/z): 980.
