Reaction Steps
0.491 g of bis(triphenylphosphine)-palladium(II)chloride, 0.371 g of triphenylphosphine and 2.6 g of imidazole are placed in a 200 ml glass autoclave, and then 8.01 g of 3-(trifluoromethyl)bromobenzene, 25 ml of formamide and 810.3 mg of diethylene glycol dibutylether are added as an internal gas chromatography (GC) standard. The autoclave is closed, flushed with nitrogen three times and then 5 bars carbon monoxide are applied. The reaction mixture is heated to 120° C. and stirred for 14 hours. The mixture is then cooled and the content determined by GC (0.8 ml of reaction mixture mixed with 5 ml of water, then 2 ml of diethylether added, and GC determination effected with the organic phase). The yield of title compound is 82% by weight.
