실험 절차

3.3 g Acetic acid 4-(5-isopropyl-[1,3,4]thiadiazol-2-ylsulfamoyl)-phenyl ester were dissolved in 12 ml dichloromethane. 2.69 ml N,N-diisopropylethylamine, 78 mg 4-dimethylaminopyridine and 2.1 g 2-(trimethylsilyl)ethoxymethyl chloride were added. The reaction mixture was stirred at room temperature for one hour. The solvent was removed in vacuo and the residue purified by flash chromatography on silica gel with the eluents n-heptane:ethyl acetate=1:1=>1:3 to obtain 2.7 g acetic acid 4-[(5-isopropyl-[1,3,4]thiadiazol-2-yl)-(2-trimethylsilanyl-ethoxymethyl)-sulfamoyl]-phenyl ester.
