実験手順
A suspension of 4-(3-hydroxy-propyl)-6-(3-methylsulfamoyl-5-trifluoromethyl-phenyl)-pyrimidine-2-carbonitrile (235 mg) and Dess Martin reagent (299 mg) in dichloromethane (5 mL) was stirred at room temperature for 2 h. The reaction mixture was purified by flash silica chromatography to afford 4-(3-methylsulfamoyl-5-tri-fluoromethyl-phenyl)-6-(3-oxo-propyl)-pyrimidine-2-carbonitrile as a pink oil (300 mg). MS m/z 399.0 (M+1), 100%.
