A solution of 8-bromo-isoquinoline (prepared by the method of F. T. Tyson, J.A.C.S., 1939, 61, 183) (1.25 g, 6 mmol) in acetic acid (5 ml) was treated with 27% aqueous hydrogen peroxide solution (1.8 ml) and heated at 75° C. overnight. The mixture was evaporated and the residue partitioned between aqueous sodium carbonate solution and dichloromethane, re-extracting with dichloromethane twice more. The combined organic extracts were dried and evaporated. The residue was triturated with ether/petrol and isolated by filtration (1.14 g, 85%).
