Reaction Conditions

Reaction Steps

0.249 g of bis(triphenylphosphine)-palladium(II) chloride, 6.51 g of (2-bromovinyl)benzene, 3.03 g of formamide, 4.78 g of 4-dimethylamino-pyridine and 25 ml of dimethylacetamide are placed in a 200 ml glass autoclave. 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 18 hours. It is then cooled, and the solution is diluted with diethylether and water, and extracted. The aqueous phase is extracted by shaking 3 times with diethylether, and afterwards the organic phases are collected, dried over magnesium sulphate and concentrated. The oil obtained is chromatographed over silica gel. The yield of title compound is 26% (part of the product remains in the water phase).
