Hexane → 2',4',6'-Trimethyl-3-nitro-biphenyl-2-carboxylic acid methyl ester

참여 물질

반응 단계

Under a nitrogen atmosphere in 20 ml of anhydrous dimethoxyethane (DME) was combined 1.44 g (5.54 mmol) of methyl 2-bromo-5-nitrobenzoate 1.68 g (11.1 mmol) of cesium fluoride and 192 mg of tetrakis(triphenylphosphine)palladium(0). The reaction was stirred for 5 minutes, at which point 1.00 g (6.09) of mesitylboronic acid was added. The solution was heated to reflux for 20 hours, and was then cooled and fractionated on silica gel using 6:1 hexane: ethyl acetate (EtOAc) to afford, after concentration in vacuo and refractionation using toluene, 5.65 g (54%) of the title compound.
