Procedure
2.12 ml of 48% aqueous hydrobromic acid are added slowly to 1.28 g of 3-(4-methoxyphenyl)cyclohexanone in 6.4 ml of acetic anhydride. After 4 hours at reflux, the reaction mixture is poured into ice-water and extracted with diethyl ether. After concentration of the organic phase and purification over silica gel, 3-(4-hydroxyphenyl)cyclohexanone is obtained in the form of an oil.
