The mixture of rac-cis-(2-bromo-5-methylphenyl)(3-methyl-2-(((5-(trifluoromethyl)pyridin-2-yl)amino)methyl)piperidin-1-yl)methanone (0.045 g, 0.097 mmol), 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (0.024 g, 0.116 mmol), P(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. oil bath. The completion of reaction was monitored by analytical 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 a crude residue, which was purified by preparative-HPLC to obtain the title compound as TFA salt. ESI-MS (m/z): 472, [M+1]+.
