110 °C

Procedure

A solution of 2.0 g (7.6 mmol) of 7-bromo-1,2,3,5-tetrahydrocyclopenta[c]quinolin-4-one, 2.6 mL (9.9 mmol) of vinyltributyltin and 0.44 g (0.38 mmol) of tetrakis(triphenylphosphine)palladium is degassed and aerated with nitrogen. After six hours of heating to 110° C., the batch is concentrated by evaporation, and the residue is taken up on silica gel. Column chromatography on silica gel with hexane-ethyl acetate yields 1.41 g of product.
