65 °C

To a flask containing methyl 3-bromo-5-hydroxybenzoate (2.1 g, 8.9 mmol) in anhydrous DMF (10 mL) was added K2CO3 (2.47 g, 17.9 mmol) and 2-iodopropane (1.07 mL, 10.7 mmol). The reaction mixture was heated at 65° C. overnight then diluted with EA and washed with NaHCO3. The organic layers were dried and concentrated to provide 1.81 g (75%) of methyl 3-bromo-5-isopropoxybenzoate as a white solid. LCMS-ESI (m/z) calculated for C11H13BrO3: 273.12; no observed m/z ion, tR=4.17 min.
