Procedure

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 morpholine (available from Aldrich Chemical Company, Inc.; 54 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′-(morpholine-4-carbonyl)-biphenyl-2-carboxylic acid (76 mg, 69%). 1H NMR (400 MHz, DMSO-d6) δ ppm 13.17 (br s, 1H), 8.46 (s, 1H), 8.37 (s, 1H), 8.33 (s, 1H), 8.24 (d, J=8.0 Hz, 1H), 8.09 (d, J=8.3 Hz, 1H), 7.76 (d, J=8.5 Hz, 1H), 7.59 (d, J=8.0 Hz, 1H), 7.44-7.51 (m, 4H), 3.60-3.67 (m, 4H), 3.26-3.30 (m, 4H).
