Komponenten

Versuchsvorschrift

To a solution of (3-aminophenoxy)-acetonitrile (1.5 g, from Example 1), triethylamine (3.22 mL) in THF (35 mL) was added dimethylsulfamoyl chloride (4.2 mL) dropwise over 10 min. After stirring at room temperature for 1 hr, the solvent was evaporated and the residue was partitioned between dichloromethane and water. The organic layer was washed with 5% HCl solution and dried over magnesium sulfate. After evaporation of the solvent, the residue was purified by flash chromatography on silica gel eluting with ethyl acetate:dichloromethane (10:90) to give N,N-dimethyl-N'-(3-cyanomethoxyphenyl)-sulfamide (1.11 g).
