실험 절차

[3,5-Bis(trifluoromethyl)-1H-pyrazol-1-yl]acetic acid (288 mg) and Hünig base (323 mg) are dissolved in dichloromethane (10 ml) and stirred at room temperature for 30 min. 4-{4-[(Cyclohexyloxy)carbonyl]-1,3-thiazol-2-yl}piperidinium chloride (X-1, 330 mg) is added, and the mixture is stirred for a further 5 min before bromo-tris-pyrrolidinophosphonium hexafluorophosphate (559 mg) is added. The reaction mixture is stirred at room temperature overnight. After removal of the solvent under reduced pressure, the residue is purified chromatographically. This gives cyclohexyl 2-(1-{[3,5-bis(trifluoromethyl)-1H-pyrazol-1-yl]acetyl}piperidin-4-yl)-1,3-thiazole-4-carboxylate (348 mg, 65%).
