Reaction Steps

A solution of 4-(4-fluorophenyl)-5-(4-(methylsulfonyl)phenyl]-1H-imidazole-2-thiol (Example 49) (100 mg, 0.29 mmol), 2-chloromethylquinoline hydrochloride (62 mg, 0.29 mmol) and triethylamine (60 mg, 0.58 mmol) in 2-propanol (5 ml) was heated at reflux under an argon atmosphere for 4 hours. The reaction was cooled, poured into water (25 ml) and extracted with ethyl acetate. After drying over sodium sulfate, the solvent was removed and the residue was purified by chromatography on silica gel using 50% ethyl acetate in toluene as the eluent to give 136 mg (85%) of the desired product. Although initially an oil, this material crystallized on standing: mp 179-182° C. Anal. Calc'd. for C26H20N3O2FS2.5H2O (MW 498.60): C, 62.63; H, 4.25; N, 8.43; S, 12.86. Found: C, 62.98; H, 4.43; N, 8.03; S, 12.60.
