Procedure
Dissolve 1-(2-isopropoxyphenyl)ethanone (1.0 g, 6 mmol) in Et2O (25 mL) and add bromine (0.3 mL, 6 mmol) drop-wise while stirring stir the mixture in the dark at ambient temperature. Wash the reaction mixture with a saturated aqueous Na2CO3 solution. Dry it over MgSO4; filter; collect the filtrate; removed the volatiles under reduced pressure to provide the title compound (1.5 g, 83%). MS (m/z): 258 (M+1).
