실험 절차

Cyclopropanecarboxylic acid (2-chloro-5-methyl-pyridin-3-ylmethyl)-ethyl-amide (0.120 g, 0.48 mmol), [4-methoxy-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-acetic acid ethyl ester (0.183 g, 0.57 mmol), and potassium carbonate (0.198 g, 1.43 mmol) were combined in DME and H2O. The mixture was purged with N2 for 10 minutes, and then tetrakis(triphenylphosphine)palladium(0) (0.055 g, 0.05 mmol) was added, and the reaction was stirred at 80° C. for 2 hours. Once no starting material was seen by analytical tlc, the mixture was diluted with H2O and extracted three times with EtOAc. The combined organic layers were washed with H2O and brine, dried over Na2SO4, decanted, and concentrated, and the residue was purified by silica gel chromatography (0-70% EtOAc in hexanes) to give the title compound.
