Participants

Reaction Steps

Using the conditions of General Procedure E for Amide Coupling in Parallel Mode, 4-[4-(3,4-dichloro-phenyl)-thiazol-2-yl]-biphenyl-2,4′-dicarboxylic acid 2-methyl ester (which may be prepared as described for Intermediate 8; 100 mg, 0.21 mmol) was reacted with 4-fluorobenzylamine (available from Aldrich Chemical Company, Inc.; 78 mg, 0.62 mmol). The resulting ester was hydrolyzed and the acid was purified using HPLC Purification Conditions B to give 4-[4-(3,4-dichloro-phenyl)-thiazol-2-yl]-4′-(4-fluoro-benzylcarbamoyl)-biphenyl-2-carboxylic acid (88 mg, 84%). 1H NMR (400 MHz, DMSO-d6) δ ppm 13.17 (br s, 1H), 9.11 (t, J=5.8 Hz, 1H), 8.46 (s, 1H), 8.38 (s, 1H), 8.33 (s, 1H), 8.24 (d, J=7.8 Hz, 1H), 8.09 (d, J=8.3 Hz, 1H), 7.96 (d, J=8.0 Hz, 2H), 7.76 (d, J=8.5 Hz, 1H), 7.59 (d, J=8.0 Hz, 1H), 7.50 (d, J=8.0 Hz, 2H), 7.35-7.41 (m, 2H), 7.16 (t, J=8.7 Hz, 2H), 4.50 (d, J=5.8 Hz, 8H).
