Sodium hydride (60% in oil, 1.44 g, 36.00 mmol) was added to a 0° C. solution of 4-hydroxybenzaldehyde (4.40 g, 36.03 mmol) in DMF (16 mL). After stirring for 20 min at 0° C., the mixture was allowed to warm to RT and a solution of 2-chloropyrimidine (4.12 g, 35.97 mmol) in DMF (8 mL) was added. The resulting mixture was heated to 100° C. for 18 h. The solvent was evaporated, the residue was dissolved in ethyl acetate, washed with water and brine, dried (MgSO4), and concentrated to provide 6.20 g (86%) of the title compound. MS 201 (M+H)+.
