反応手順

160 mL of THF were placed in the flask and degassed with argon. Then 10 g (45 mmol) 5-fluoro-2-iodo-aniline, 1.5 g (2.1 mmol) PdCl2(PPh3)2 and 0.40 g (2.1 mmol) copper iodide were added and the flask was rinsed with argon. Then 18 mL (0.13 mol) triethylamine were added and 3.0 g (55 mmol) 1-butyne (in gaseous form) were passed through the solution. The reaction mixture was stirred for 3 h at RT, then diluted with diethyl ether, filtered through kieselguhr and evaporated down.
