Procedure

(S)-3-(4′-Cyano-biphenyl-4-yl)-2-({(3R,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 (94 mg) was reacted with 2-acetylamino-4-methyl thiazole-5-sulfonyl chloride (64 mg) according to General Procedure E to obtain (S)-2-({(3R,8S)-7-(2-acetylamino-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 (16 mg). This was hydrolyzed according to General Procedure B to give the title compound (11 mg). LCMS: (m/z) 955. 1H NMR (400 MHz, DMSO-d6): 7.80-7.75 (m, 4H), 7.71 (d, 1H), 7.66-7.64 (m, 3H), 7.54 (d, 2H), 7.45 (d, 1H), 7.32 (d, 2H), 7.10 (d, 1H), 7.04-7.02 (m, 2H), 6.72 (s, 1H), 6.63 (s, 1H), 5.57-5.56 (m, 2H), 5.53-5.52 (m, 1H), 5.14 (s, 2H) 5.02-4.99 (m, 1H), 4.55-4.53 (m, 1H), 4.35-4.29 (m, 1H), 4.27-4.20 (m, 3H), 3.94-3.89 (m, 1H), 3.74-3.70 (m, 2H), 2.95-2.92 (m, 1H), 2.48 (s, 3H).
