Product 1

HCID 66719781(S)-3-(4'-cyano-biphenyl-4-yl)-2-({(S)-3-[4-(3,4-dichloro-benzyloxy)-phenyl]-7-pyridin-2-ylmethyl-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-({(S)-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 (40 mg) was treated with pyridine-2-carbaldehyde according to General Procedure D to give (S)-3-(4′-cyano-biphenyl-4-yl)-2-({(S)-3-[4-(3,4-dichloro-benzyloxy)-phenyl]-7-pyridin-2-ylmethyl-2,3,6,7,8,9-hexahydro-[1,4]dioxino[2,3-g]isoquinoline-8-carbonyl}-amino)-propionic acid methyl ester (42 mg). LCMS (m/z): 842. The methyl ester (25 mg) was hydrolyzed according to General Procedure B to give the title compound (20 mg). LCMS (m/z): 827.
