Procedure

2′-Nitrobiphenyl (5 g) was added slowly to chlorosulfonic acid (25 mL) at room temperature and stirring was continued for 2 hours. The mixture was carefully dripped into ice water and extracted with DCM. The solvent was evaporated and the residue purified by column chromatography (petrol/ethyl acetate) to give the title compound as a yellow oil.
