Ethanol → 5-(2,3-Difluoro-4-octylphenyl)-2-(6-octyloxypyridin-3-yl)pyrimidine

Participants

Reaction Steps

The reaction of 3.5 mmol of 5-bromo-2-(6-octyloxypyridin-3-yl)pyrimidine, 3.85 mmol of 2,3-difluoro-4-octylphenylboronic acid, 7 mmol of sodium carbonate and 0.04 mmol of tetrakis(triphenylphosphine)palladium(0) in 20 ml of toluene: 10 ml of ethanol and 10 ml of water it carried out analogously to the procedure indicated for Example 1a). The crude product is separated off by column chromatography on silica gel 60 using heptane/ethyl acetate 9:1 (v/v) as eluent and is recrystallized from acetonitrile, giving 1.5 g (83%) of colorless crystals, X 105 SC 104 SA 127 I.
