Product 1

HCID 86654923(S)-3-(4'-cyano-biphenyl-4-yl)-2-{[(3S,8S)-3-[4-(3,4-dichloro-benzyloxy)-phenyl]-7-(4-methoxy-2-nitro-benzenesulfonyl)-2,3,6,7,8,9-hexahydro-[1,4]dioxino[2,3-g]isoquinoline-8-carbonyl]-amino}-propionic acid methyl ester

Procedure

(S)-3-(4′-Cyano-biphenyl-4-yl)-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)-propionic acid methyl ester (20 mg) was reacted with 4-methoxy-2-nitro-benzenesulfonyl chloride to give (S)-3-(4′-cyano-biphenyl-4-yl)-2-{[(3S,8S)-3-[4-(3,4-dichloro-benzyloxy)-phenyl]-7-(4-methoxy-2-nitro-benzenesulfonyl)-2,3,6,7,8,9-hexahydro-[1,4]dioxino[2,3-g]isoquinoline-8-carbonyl]-amino}-propionic acid methyl ester according to General Procedure E. This product (5 mg) was hydrolyzed according to General Procedure B to give the title compound (4 mg). LCMS (m/z): 951.
