실험 절차

2-bromo-4,6-bis(trifluoromethyl)benzaldehyde (100 mg, 0.31 mmol), ethyl 3-(5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)picolinamido)propanoate (119 mg, 0.34 mmol), Pd(dppf)Cl2 (23 mg, 0.03 mmol), and 2M K2CO3 (0.31 mL, 0.62 mmol), were dissolved in 1,4-dioxane (1.0 mL) and heated to 100° C. After 70 min the resulting mixture was cooled to room temperature, diluted with DCM, dried (Na2SO4), concentrated and purified via column chromatography to yield the title compound.
