Versuchsvorschrift

A mixture of 1-bromo-2-fluoro-3-(methoxymethoxy)benzene (17.9 g), (4-fluorophenyl)boronic acid (16.0 g), tris(dibenzylideneacetone)dipalladium(0) (3.49 g), a 2 M aqueous sodium carbonate solution (114 mL), dicyclohexyl(2′,6′-dimethoxybiphenyl-2-yl)phosphine (3.13 g), and toluene (180 mL) was stirred at 100 C for 2 hours in a nitrogen atmosphere. The reaction mixture was cooled to room temperature and then passed through celite. The organic layer was separated, and the solvent was distilled off under reduced pressure. The obtained residue was passed through a short silica gel (NH) column, and the solvent was distilled off under reduced pressure to obtain the title compound (19.0 g).
