실험 절차

30 mg of 6-thiophen-3-yl-2-(2-trimethylsilanylethoxymethyl)-4-[1-(2-trimethylsilanyl -ethoxymethyl)-1H-benzimidazol-2-yl]-2H-pyridazin-3-one is dissolved in a mixture of dichloromethane (1 ml) and trifluoroacetic acid (1 ml), 18 μl of ethanedithiol are added, and the resulting solution is stirred at room temperature for 18 hours. After the solvent has been distilled off, the crude product is purified by preparative RP-HPLC (0-100% acetonitrile (+0.05% formic acid) in water (+0.05% formic acid)).
