Reaktionsschritte

To methyl 3,5-dibromo-4-(trifluoromethoxy)benzoate (500 mg, 1.32 mmol), Cs2CO3 (2586 mg, 7.94 mmol), Pd(OAc)2 (11.9 mg, 0.053 mmol), potassium cyclopropyltrifluoroborate (470 mg, 3.18 mmol) and di(1-adamantyl)-n-butylphosphine (28.5 mg, 0.079 mmol) was added toluene (12 mL) and water (1.2 mL). The reaction mixture was heated to 100° C. overnight. The reaction mixture was cooled to room temperature, diluted with water, extracted with DCM and evaporated in vacuo. The residue was purified by silica gel chromatography (0-20% EtOAc/hexanes) to yield the title compound (259 mg).
