Procedure
A solution of 1-(4-fluorophenyl)-2-((2,3,6-trifluorobenzyl)thio)-1H-imidazole-5-carboxylic acid (11) (261 mg, 0.68 mmol) in acetone (7 mL) was added 0.2 M NaHCO3 (7 mL) and Oxone (1.05 g, 1.71 mmol) and stirred at room temperature for 2 h. Water was added and the mixture was extracted with ethyl acetate. The combined organic layers were washed with water, dried over sodium sulfate, filtered and concentrated in vacuo to obtain 1-(4-fluorophenyl)-2-((2,3,6-trifluorobenzyl)sulfinyl)-1H-imidazole-5-carboxylic acid (20) as a white solid.
