実験手順: To a solution of 6-(4-{[3,5-bis(difluoromethyl)-1H-pyrazol-1-yl]acetyl}piperazin-1-yl)-pyridine-2-carboxylic acid (150 mg) in dichloromethane (5 ml) are added, at room temperature, 1,2,3,4-tetrahydronaphthalen-1-ol (70 mg), 4-dimethylaminopyridine (4.4 mg) and 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide (104 mg). The mixture is stirred at room temperature overnight, and then water is added. The aqueous phase is removed and extracted with ethyl acetate, and then the combined organic phases are dried over sodium sulphate. The solids are filtered off and the solvent is distilled off. The residue is purified by chromatography. This gives 1,2,3,4-tetrahydronaphthalen-1-yl 6-(4-{[3,5-bis(difluoromethyl)-1H-pyrazol-1-yl]acetyl}piperazin-1-yl)pyridine-2-carboxylate (70 mg).

実験手順: At room temperature, 1,2,3,4-tetrahydronaphthalen-1-ol (155 mg) and triphenylphosphine (758 mg) are added to a solution of 2-(1-{[5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl}piperidin-4-yl)-1,3-thiazole-4-carboxylic acid (III-4, 380 mg) in tetrahydrofuran (2.5 ml). The mixture is stirred at 0 C under argon for 5 minutes, and diethyldiazene 1,2-dicarboxylate (383 mg) is then added dropwise. The reaction mixture is slowly warmed to room temperature. After 2 hours, the solvent is removed under reduced pressure and the residue is purified chromatographically. This gives 1,2,3,4-tetrahydronaphthalen-1-yl 2-(1-{[5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl}piperidin-4-yl)-1,3-thiazole-4-carboxylate (196 mg, 39%). After 2 hours the solvent is removed under reduced pressure the residue is purified chromatographically
