Reaktionsschritte

A multinecked flask as described in Example 1 was charged with 50.0 g (0.28 mol) of p-bromofluorobenzene, 200 ml of dried, degassed triethylamine, 35.0 g (0.30 mol) of 3-aminophenylacetylene, 0.23 g (0.29 mmol) of bis(triphenyl phosphine) palladium II chloride, 1.03 g (3.92 mmol) of triphenylphosphine, and 0.1 g (0.52 mmol) of cuprous iodide. The reaction mixture was heated at 65° C. for 48 hours at which point gas chromatography showed the reaction to be complete. The mixture was cooled to room temperature and diluted with 200 ml of toluene. The toluene/triethylamine solution was decanted and concentrated on the rotary evaporator to give 75 g (0.27 mol, 96% yield) of the product as a bright yellow solid.
