Reaction Steps
To a solution of 5,6-dimethoxysaccharin (0.8 g) in dichloromethane (100 ml) was added triethyloxonium tetrafluoroborate (3.5 ml, 1M soln in CH2Cl2) and the solution stirred at room temperature for 3 hrs. After extraction with aqueous sodium bicarbonate, the organic phase was dried and concentrated. Purification by column chromatography (silica, chloroform) gave the title compound (0.2 g).
