In a manner similar to that described for Examples 16C-D, the title compound was prepared from 5-(4-fluorophenyl)-2-methyl-1-(2-trifluoromethylphenyl)-1H-pyrrole-3-carboxylic acid ethyl ester, which was synthesized from 2-trifluoromethyl-aniline and 2-acetyl-4-(4-fluorophenyl)-4-oxobutyric acid ethyl ester using the procedures described in WO 03/027069. 1H-NMR (CDCl3): δ 7.92-7.84 (5H, m), 7.77-7.69 (2H, m), 7.63-7.60 (1H, m), 7.42 (1H, d), 7.07-7.03 (2H, m), 6.88-6.84 (2H, m), 6.60 (1H, s), 3.05 (3H, s), 2.33 (3H, s). MS (ESI): 517 (MH+). B. In a manner similar to that described for Example 20A, but replacing 2-trifluoromethyl-aniline with 4-fluoroaniline, the following compound was prepared: 1,5-bis-(4-fluorophenyl)-2-methyl-1H-pyrrole-3-carboxylic acid (4-methanesulfonyl-phenyl) amide; 1HNMR (CDCl3): δ 7.93-7.80 (5H, m), 7.25-7.11 (4H, m), 7.09-7.01 (2H, m), 6.93-6.87 (2H, m), 6.56 (1H, s), 3.04 (3H, s), 2.45 (3H, s). MS (ESI): 467 (MH+). C. In a manner similar to that described for Example 20A, but replacing 4-methanesulfonyl-aniline with the appropriate amines in the last step, the following compounds were prepared:
