Sodium Carbonate → 5-(6-Butoxypyridin-3-yl)-2-(2,3-difluoro-4-octylphenyl)pyrimidine

Participants

Reaction Steps

The reaction of 2 mmol of 5-(6-butoxypyridin-3-yl)-2-chloropyrimidine, 2.2 mmol of 2,3-difluoro-4-octylphenylboronic acid, 4 mmol of sodium carbonate and 0.02 mmol of tetrakis(triphenylphosphine)palladium(0) in 10 ml of toluene, 5 ml of ethanol and 5 ml of water is 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 0.42 g (46%) of colorless crystals, X 84 SC 73 SA 162 I.
