Reaktionsschritte

To a degassed solution of ethyl 3,5-bis(trifluoromethyl)-phenylphosphinate (3.33 g, 15.24 mmol) and 4-bromo-1-isopropoxy-2-vinylbenzene (3.33 mg, 13.8 mmol) in DMF (25 mL) were added the triethylamine (3.85 mL, 27.6 mmol) and tris(dibenzylideneacetone)dipalladium (2.53 g, 2.76 mmol). The mixture was heated in an oil bath at 70° C. overnight. The volatiles were removed in vacuo and the mixture was purified by column chromatography with 20 to 70% ethyl acetate in petroleum ether to afford compound BA3 (185 mg) as an oil in 2.8% yield.
