Reaktionsschritte

Benzyl-ethyl-carbamic acid 2-bromo-5-trifluoromethyl-benzyl ester (0.354 g, 0.85 mmol), [4-methoxy-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-acetic acid ethyl ester (0.300 g, 0.94 mmol), and potassium carbonate (0.410 g, 2.98 mmol) were combined in a deoxygenated solution of DME (8 mL) and H2O (4 mL). Tetrakis(triphenylphosphine)palladium(0) (0.100 g, 0.09 mmol) was added, and the reaction was stirred at 75° C. for 2 hours. After work-up, the crude material was purified by silica gel chromatography (0-50% EtOAc in hexanes) to give the title compound.
