Reaction Steps

Ethyl 4-bromo-3-hydroxybenzoate (prepared according to M. I. Dawson et al WO 2003048101; 0.5 g, 2.04 mmol), potassium carbonate (0.84 g, 6.12 mmol) and iodoethane (0.2 mL, 2.45 mmol) were placed in 50 mL DMF and the reaction was heated at 80° C. for 18 h. The mixture was cooled and partitioned between EtOAc and water. The organic layer was separated, washed with water, brine, dried (Na2SO4), filtered, and the filtrate was concentrated under vacuum to an oil. The oil was purified by column chromatography using EtOAc/hexane (0-50%) as eluent to give the product (0.35 g, 62%) as a clear oil.
