Reaction Steps
Ethyl 2-bromo-2-methyl-propanoate and p-chlorophenol was dissolved in dry acetone and treated with potassium carbonate. After stirring at rt for 30 min., the mixture was refluxed for 16 h. The reaction mixture was poured into water and extracted with DCM. The organic layer was dried over MgSO4, filtered and concentrated. The residue was purified by flash chromatography (silica, hexanes:EtOAc, 9:1, 6:1 to 3:1) to give the desired product, which was used in the following step without further purification.
