Reaction Steps

1-(4-Methoxy-phenyl)-cyclopropanecarboxylic acid [5-(2-chloro-phenylsulfanyl)-thiazol-2-yl]-amide (50.0 mg, 0.120 mmol) was dissolved in 3 mL of acetic acid containing hydrogen peroxide (30% aqueous solution, 40.8 mg, 0.360 mmol). The mixture was warmed to 85° C. for 1 hour. Ether (1.5 mL) and water (1.5 mL) was added and the layers were separated. the organic layer was dried over sodium sulfate, filtered, and evaporated to dryness. The crude reaction mixture was then separated by reverse-phase preparative liquid chromatography to yield the pure product (20.9 mg, 0.0483 mmol, 40.2%). ESI-MS m/z calc. 432.0. found; 433.3 (M+1)+ Retention time 3.34 minutes.
