PROCEDURE

实验过程

The reaction of 2.5 mmol of 2-chloro-5-(6-hexyloxypyridin-3-yl)pyrimidine, 2.5 mmol of 2,3-difluoro-4-octylphenylboronic acid, 5 mmol of sodium carbonate and 0.025 mmol of tetrakis(triphenylphosphine)palladium(0) in 8 ml of toluene, 4 ml of ethanol and 4 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 dichloromethane/ethyl acetate 98:2 (v/v) as eluent and is recrystallized from acetonitrile, giving 0.47 g (39%) of colorless crystals, X 94.5 SC 125.5 SA 156 I.
