Reaction Steps

To a stirred solution of 5-(4-methoxyphenyl)cyclohexane-1,3-dione (5 g, 22.6 mmol) in AcOH (40 mL) at r.t. was added bromine (3.61 g, 1.18 mL, 22.6 mmol) dropwise. The reaction was then carried out according to Method A to give the title compound in quantitative yield as a white solid. δH (DMSO-d6) 7.24 (2H, d, J 8.6 Hz), 6.87 (2H, d, J 8.6 Hz), 3.72 (3H, s), 3.31-3.21 (1H, m), 2.88-2.82 (2H, m), 2.77-2.62 (3H, m). LCMS (ES+) 296.9 (M+H)+.
