반응 단계

A mixture of (2-bromo-5-methylphenyl)((2S,3R)-3-methyl-2-(((5-(trifluoromethyl)pyridin-2-yl)amino)methyl)piperidin-1-yl)methanone (0.045 g, 0.097 mmol), tert-butyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole-1-carboxylate (0.034 g, 0.116 mmol), Pd(PPh3)4 (0.017 g, 0.015 mmol), K2CO3 (0.4 g, 0.291 mmol) and dioxane/H2O (4:1, 3 mL) was degassed for 5 min and heated overnight at 100° C. The completion of the reaction was monitored by anal. HPLC. The mixture was cooled and extracted with EtOAc. The combined organic layers were washed with saturated NaHCO3 and dried over Na2SO4. The solvent was removed in vacuo to obtain the crude, which was purified by preparative-HPLC to obtain the title compound as TFA salt. ESI-MS (m/z): 458 [M+1]+.
