To Montmorinonite (415 mg) was added H2O (98 μL) the mixture was stirred for 10 min before DCM (0.5 mL), oxone (428 mg, 0.70 mmol) and 2-{2-[3-[2-(4-methoxy-phenyl) -ethyl]-3-(trans-4-methyl-cyclohexyl)-ureido]-thiazol-5-ylsulfanyl}-2-methyl-propionic acid (129 mg, 0.278 mmol) suspended in DCM (2.6 mL) was added in seqence. The mixture was stirred at rt for 1.5 hs. LCMS showed a 1:1 mixture of the sulfoxide and sulfone. The reaction mixture was filtered, washed with DCM and the filtrate was concentrated in vacuo. The mixture was purified by HPLC to give37 mg of {2-[3-[2-(4-methoxy-phenyl)-ethyl]-3-(trans-4-methyl-cyclohexyl)-ureido]-thiazole-5-sulfinyl}-acetic acid.
