To a solution of 199 μl of bromobenzene (1.88 mmol) and 361 μl of benzenesulphonyl chloride (2.83 mmol) in 4 ml of trifluoroacetic acid there are added, in succession, 83 mg of indium chloride (0.376 mmol) and then, dropwise, 25 μl of trifluoromethanesulphonic acid. The reaction mixture is stirred for 2 hours at 70° C. and is then returned to ambient temperature and diluted with ice-cold water. After rendering alkaline to pH 10 by adding concentrated sodium hydroxide solution, the reaction mixture is extracted with CH2Cl2. The organic phases are collected, washed with saturated NaCl, dried (MgSO4) and evaporated under reduced pressure to yield the title product in the form of a white solid.
