Versuchsvorschrift

To a solution of crude 1-(phenoxymethyl)-2-sulfamoylbenzene (1.6 g, 6 mmol.) in 200 mL of methanol was added Pd/C (0.64 g). The reaction mixture was stirred at room temperature for 5 hours under H2 with a pressure of 30 psi. After the material was consumed, the reaction mixture was filtered. The solvent was evaporated to give crude 1-(hydroxy)-2-sulfamoylbenzene (800 mg, 80%) which was used directly without purification.
