Procedure

A mixture of 4-fluorobenzaldehyde (0.196 mL, 1.828 mmol), 2-(trifluoromethyl)-5-pyrimidinol (300 mg, 1.828 mmol), and K2CO3 (505 mg, 3.66 mmol) in DMF (2 mL) was heated with a microwave reactor at 130° C. for 1 h. After removing the solvent, the residue was diluted with water, extracted with DCM. The organic phase was dried over sodium sulfate, filtered, and concentrated. Purification via flash chromatography then afforded the title compound (351 mg, 1.309 mmol, 71.6% yield). LCMS: rt=2.97 min, [M+H+]=269
