Sodium Carbonate → Methyl 4'-fluoro-3-isopropoxybiphenyl-4-carboxylate

Participants

Reaction Steps

A mixture of methyl 4-iodo-2-isopropoxybenzoate (7.50 g), (4-fluorophenyl)boronic acid (6.56 g), dicyclohexyl(2′,6′-dimethoxybiphenyl-2-yl)phosphine (1.44 g), a 2 M aqueous sodium carbonate solution (35.1 mL), tris(dibenzylideneacetone)dipalladium(0) (1.50 g), and toluene (50 mL) was stirred at 100 C for 2 hours in an argon atmosphere. The reaction mixture was allowed to cool to room temperature. Then, the organic layer was separated and passed through a short silica gel (NH) column, and the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate) to obtain the title compound (6.61 g).
