HCID 669114853,3-Dimethylbutyl 2-(1-{[3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl}piperidin-4-yl)-1,3-thiazole-4-carboxylate

Procedure

A solution of 2-(1-{[3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl}piperidin-4-yl)-1,3-thiazole-4-carboxylic acid (III-2, 200 mg) is reacted analogously to Example I-811 with 3,3-dimethylbutan-1-ol (68.0 mg). This gives, after chromatographic purification, 3,3-dimethylbutyl 2-(1-{[3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl}piperidin-4-yl)-1,3-thiazole-4-carboxylate (98 mg, 40%).
