Procedure

2-(2,4-dichlorophenyl)-1-(4-hydroxyphenyl)-5-methyl-N-[5-(trifluoromethyl)pyridin-2-yl]-1H-imidazole-4-carboxamide (136 mg, 0.27 mmol) and triethylamine (40 μl, 0.32 mmol) in dichloromethane (4.0 ml) were cooled to −78° C. 3,3,3-trifluoropropane-1-sulfonyl chloride (63 mg, 0.32 mmol) was carefully added to the reaction mixture. The resulting mixture was stirred at −78° C. for 1 h, and then allowed to reach room temperature. Water was added to the reaction, and the phases were separated. The organic phase was washed with NaHCO3, brine and dried with Na2SO4. The solvent was removed under reduced pressure and separation by preparatory HPLC gave the title compound (88 mg, 49%) as a solid.
