To a solution of 2-(2,3,6-trifluorophenyl)propan-2-ol (74) (0.73 g, 3.8 mmol) and ethyl 1-(4-fluorophenyl)-2-mercapto-1H-imidazole-5-carboxylate (6) (1.12 g, 4.2 mmol) in CH2Cl2 (5 mL) was added zinc iodide (1.7 g, 5.3 mmol) at room temperature. The mixture was stirred at room temperature overnight. The reaction was diluted with EtOAc and washed with 0.5 N NaOH, water, brine, dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel to afford ethyl 1-(4-fluorophenyl)-2-((2-(2,3,6-trifluorophenyl)propaN-2-yl)thio)-1H-imidazole-5-carboxylate. (75).
