Procedure

3-Cyclopentanesulfanyl-4-nitrotoluene (0.47 g, 2.0 mmol) was oxidized to 3-cyclopentanesulfinyl-4-nitrotoluene (0.46 g, 91%) following general procedure R (using one equivalent of m-CPBA). 3-Cyclopentanesulfinyl-4-nitrotoluene was reduced to 2-cyclopentanesulfinyl-4-methyl-aniline (0.33 g, 81%) following general procedure C. 1-(2-Cyclopentanesulfinyl-4-methyl-phenyl)-3-thiazol-2-yl-urea (225 mg, 65%) was prepared from 2-cyclopentanesulfinyl-4-methyl-aniline (223 mg, 1.0 mmol) and 2-aminothiazole (100 mg, 1.0 mmol) following the general procedure D.
