실험 절차
The compound was synthesized using ethyl 3-(trifluoromethyl)-1H-pyrazole-4-carboxylate and 1-(5-ethylpyrimidin-2-yl)piperidin-4-yl methanesulfonate in a manner similar to that described in Intermediate 1, Step 1. The reaction afforded two regioisomers, ethyl 1-(1-(5-ethylpyrimidin-2-yl)piperidin-4-yl)-3-(trifluoromethyl)-1H-pyrazole-4-carboxylate and ethyl 1-(1-(5-ethylpyrimidin-2-yl)piperidin-4-yl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxylate which were separated by flash column chromatography on silica gel.
