Reaction Steps

To a solution of 2-[3,5-bis(difluoromethyl)-1H-pyrazol-1-yl]-1-(4-{4-[5-(2-hydroxyphenyl)-4,5-dihydro-1,2-oxazol-3-yl]-1,3-thiazol-2-yl}piperidin-1-yl)ethanone (150 mg) and triethylamine (33 mg) in methylene chloride (10 ml) is added, at 0° C., a solution of cyclohexanecarbonyl chloride in methylene chloride (2 ml). The ice bath is removed and the reaction mixture is stirred at 0° C.-RT for 3 h. Then the mixture is admixed with dilute sodium hydrogencarbonate solution and extracted with methylene chloride. The combined organic phases are dried over sodium sulphate and concentrated. Purification by column chromatography gives 2-{3-[2-(1-{[3,5-bis(difluoromethyl)-1H-pyrazol-1-yl]acetyl}piperidin-4-yl)-1,3-thiazol-4-yl]-4,5-dihydro-1,2-oxazol-5-yl}phenyl cyclohexanecarboxylate (150 mg).
