実験手順

A mixture of 5-benzylsulfamyl-2-(biphenyl-2-yloxy)-benzonitrile (Preparation 56, 6.06 g, 15.4 mmol), dichloromethane and aq HCl was stirred vigorously with cooling (ice bath). Sodium hypochlorite was added dropwise over 30 minutes and stirring continued with cooling for 1 hour. The layers were separated, the aqueous extracted with dichloromethane (2×100ml), and the organic collected, dried (MgSO4) and concentrated in vacuo. The residue was purified using silica gel column chromatography (ethyl acetate:Heptane 10/90 to 20/80) to furnish 4.58 g of the title compound. 1HNMR (CDCl3): δ 6.7 (m, 1H), 7.2-7.6 (m, 9H), 7.85 (m, 1H), 8.15 (m, 1H).
