Procedure

To a solution of 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-oxazole-5-carboxylic acid (E, 160 mg) in dichloromethane (5 ml) are added, at room temperature, 2-chlorocyclohexanol (57 mg), 4-dimethylaminopyridine (4 mg) and 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (94 mg). The mixture is stirred overnight, and water is then added. The aqueous phase is removed and extracted with ethyl acetate. The combined organic phases are dried over sodium sulfate. The solids are filtered off and the solvent is distilled off. The residue is purified by chromatography. This gives 2-chlorocyclohexyl 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-oxazole-5-carboxylate (100 mg, 50%).
