Reaction Steps

At room temperature, 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane 2,4-disulfide (88 mg) is added to a solution of cyclohexyl 2-(1-{[3,5-bis(difluoromethyl)-1H-pyrazol-1-yl]acetyl}piperidin-4-yl)-1,3-thiazole-4-carboxylate (I-811, 200 mg) in 1,2-dimethoxyethane (1 ml) and chloroform (0.4 ml). The reaction mixture is stirred at 70-80° C. overnight. After removal of the solvent under reduced pressure, the residue is purified chromatographically. This gives cyclohexyl 2-(1-{2-[3,5-bis(difluoromethyl)-1H-pyrazol-1-yl]ethanethioyl}piperidin-4-yl)-1,3-thiazole-4-carboxylate (80 mg, 39%).
