Reaction Steps

At ambient temperature, to a stirred solution containing 4-(2-chlorobenzoyl)-2-ethylphenol (13.62 g, 52.24 mmol) and pyridine (0.25 mL, 3.23 mmol) in CH2Cl2 (870 mL) was added dropwise bromine (3.3 mL, 62.29 mmol). After 48 h, the reaction was washed with 10% aq. Na2SO4 (1×180 mL), H2O (2×350 mL), brine (1×300 mL), dried (Na2SO4) and concentrated to give 16.50 g (93%) of the title compound. 1H NMR: consistent.
