Reaktionsschritte

A mixture of 1-(2-chlorophenyl)ethanone (1.4 mL, 10.8 mmol), 4-bromo-1-chloro-2-(methyloxy)benzene (2.0 g, 9.0 mmol), sodium tert-butoxide (2.2 g, 22.6 mmol), palladium(II) acetate (20.3 mg, 0.1 mmol), and 2-(dicyclohexylphosphino)-2′-methylbiphenyl (65.8 mg, 0.2 mmol) in 30 mL of toluene was degassed and stirred at 80° C. for 16 h. The reaction mixture was cooled and a mixture of Et2O (100 mL) and H2O (100 mL) was added. The aq layer was separated and extracted with Et2O (3×50 mL). Organic layers were combined, dried over MgSO4, and concentrated. Chromatography on a Biotage 40+M cartridge using 1:9 v/v EtOAc/hexanes as the eluant afforded the product: 1H NMR δ 3.87 (s, 3H), 4.22 (s, 2H), 6.75 (dd, J=1.7, 8.2, 1H), 6.81 (d, J=1.6, 1H), 7.26-7.31 (m, 2H), 7.37-7.43 (m, 3H).
