Reaction Steps

Potassium carbonate (1.20 g, 8.66 mmol), o-cresol (468 mg, 4.33 mmol), copper powder (28 mg, 0.43 mmol) and 3-bromo-4-methoxybenzoic acid (1.00 g, 4.33 mmol) were suspended in DMF (5 ml) and heated to 165° C. overnight. Potassium carbonate (1.20 g, 8.66 mmol) and o-cresol (468 mg, 4.33 mmol) were added once again and heating was continued for another 2 h. The crude mixture was partitioned between EA and 2 N hydrochloric acid, the aqueous phase extracted with EA, and the combined organic phases were dried over magnesium sulfate, filtered and evaporated to dryness. The residue was purified by silica gel chromatography (HEP/EA gradient) to yield 600 mg of the title compound.
