Reaction Steps

1M aq. Na2CO3 (20 mL) and ethanol (10 mL) were added to a solution of 2-chloro-4-methoxypyrimidine (2.90 g, 20.06 mmol, prepared as described in Tetrahedron 1997, 53, 11595), 4-formylphenylboronic acid (3.90 g, 26.01 mmol) and [1,4-bis(diphenylphosphino)butane]palladium(II) dichloride (0.60 g, 0.99 mmol) in toluene (40 mL) and the mixture was heated to reflux for 18 h. The cooled reaction mixture was diluted with ethyl acetate, washed with sat. aq. NaHCO3 and brine, dried (MgSO4), and concentrated. Purification by chromatography (SiO2, 4:1 hexane/ethyl acetate) yielded 1.80 g (42%) of the title compound. MS 215 (M+H)+.
