Procedure
To a stirred solution of spiro[5,5]undecane-2,4-dione (1.29 g, 5 mmol) in AcOH (10 mL) at r.t. was added bromine (0.8 g, 0.25 ml, 5 mmol) dropwise. The reaction was carried out according to Method A to give the title compound in quantitative yield as a light brown solid which was used without further purification. LCMS (ES+) 258.9 (M+H)+.
