To a stirred solution of methyl 5-hydroxy-4′-methylbiphenyl-3-carboxylate (300 mg, 1.24 mmol) in tetrahydrofuran (20 mL) at 0° C. was added sodium hydride (60% in mineral oil, 55 mg, 1.37 mmol) over a period of 10 minutes. The reaction mixture was concentrated to afford a green solid. A microwave vial was charged with the resulting green solid, dimethyl sulfoxide (8 mL), and 2-chloropyrimidine (118 mg, 0.98 mmol). The mixture was subjected to microwave irradiation at 100° C. for 4 minutes. After cooling, the mixture was filtered through Celite and the filtrate was concentrated. The residue was purified by flash chromatography to afford the title compound.
