Reaction Steps

1.0 g of 3-(4-trifluoromethylphenoxysulfonyl)-1,2,4-triazole synthesized by a method similar to that employed to prepare the precursor according to Reference Example 3 was dissolved in 10 ml of acetonitrile. Then, 0.57 g of potassium carbonate anhydride was added, and 0.59 g of dimethylsulfamoyl chloride was gradually added at room temperature while stirring the solution. The solution was then refluxed for one hour, and the reactant solution was poured into water and extracted with ethyl acetate. The organic layer was washed with brine and dried with magnesium sulfate, and then the solvent was removed by distillation and the residue was purified by silica gel chromatography. As a result, 1.18 g of the titled compound was obtained.
