Reaction Steps
A mixture of Na2CO3 (4.74 g, 44.72 mmol) and 3-formylphenylboronic acid (3.40 g, 22.67 mmol) in water (15 mL) were added to a solution of 2-bromopyrimidine (3.00 g, 18.87 mmol) and tetrakis(triphenylphosphine)palladium(0) (0.72 g, 0.62 mmol) in DME (30 mL) and the mixture was heated to reflux for 24 h. The cooled reaction mixture was diluted with dichloromethane, washed with sat. aq. NaHCO3 and brine, dried (MgSO4), and concentrated. Purification by chromatography (SiO2, 1:1 hexane/ethyl acetate) yielded 2.20 g (63%) of the title compound. MS 185 (M+H)+.
