Reaction Steps

At room temperature, 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane 2,4-disulfide (194 mg) was added to a solution of 2-[3,5-bis(difluoromethyl)-1H-pyrazol-1-yl]-1-{4-[4-(cyclohexylacetyl)-1,3-thiazol-2-yl]piperidin-1-yl}ethanone (200 mg) in toluene (2 ml). The reaction mixture was stirred at 60° C. for 2 hours. After removal of the solvent under reduced pressure, the residue was purified chromatographically. This gave 1-[2-(1-{2-[3,5-bis(difluoromethyl)-1H-pyrazol-1-yl]ethanethioyl}-piperidin-4-yl)-1,3-thiazol-4-yl]-2-cyclohexylethanone (101 mg, 49%).
