실험 절차

140 mg of [5- (3,5-dichlorophenylthio)-1 -(4-methoxybenzyl)-3-methyl-1H-pyrazol-4-yl ]-phenyl-methanone was treated with 4 ml of trifluoroacetic acid. The solution was then heated at reflux for 2 h. The solvent was evaporated under reduced pressure. The residue was then partitioned between dichloromethane/saturated sodium hydrogen carbonate, washed with brine then dried over anhydrous magnesium sulphate, filtered and evaporated to give 75 mg of [5-(3,5-dichlorophenylthio)-3-methyl-1H-pyrazol-4-yl]-phenyl-methanone as a yellow solid which was used without further purification. Mass spectrum (ES) m/z 363[M+H]+.
