Participants

Reaction Conditions

Reaction Steps

4-Methoxycarbonylphenyl boronic acid (0.5 g) and 5-bromo-2-pyridinecarbonitrile (0.5 g) in a mixture of THF (5 ml) and water (5 ml) were treated with tetrakis(triphenyl phosphine)palladium(0) (0.32 g) and potassium carbonate (1 g). A further amount of THF (5 ml) was added and the reaction was heated at 80° C. for 1 h. After cooling the reaction mixture was diluted with EtOAc (30 ml) and washed with saturated aqueous sodium hydrogen carbonate solution. The organic layer was dried (magnesium sulfate) and concentrated to give a crude residue that was purified by column chromatography (silica-gel, gradient 0-100% EtOAc in hexane) to give the title compound (D8) as a white solid (0.5 g). LCMS electrospray (+ve) 239 (MH+).
