Reaction Conditions

Temperature	150 °C

Reaction Steps

A mixture of methyl 4-iodobenzoate (0.421 g, 1.6 mmol), 2,4-dihydroxypyridine (0.174 g, 1.34 mmol), CuI (25 mg, 0.134 mmol) and K2CO3 (200 mg) in DMF (2 mL) was heated to 150° C. in a sealed vial for 4 hours, diluted with ethyl acetate (100 mL), washed with water (30 mL) and brine (30 mL), dried (Na2SO4), filtered, and concentrated. The concentrate was purified by flash column chromatography on silica gel with 2:1 hexanes/ethyl acetate to provide the desired product. MS (APCI) m/e 246 (M+H)+.
