Reaction Steps
Ethyl 4-bromo-3-hydroxybenzoate (1.5 g, 6.12 mmol), potassium carbonate (5.07 g, 36.72 mmol) and 1-chloro-2-methylpropan-2-ol (0.75 mL, 7.34 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. Purification by column chromatography on silica gel using EtOAc/hexane (0-50%) gave the product (0.5 g, 26%) as a yellow oil.
