실험 절차

To a suspension of 1-hydroxy-2-(3,4-dimethoxyphenyl)-4-methyl-5-(3-pyridyl)imidazole (0.68 g) in methylene chloride (9 ml) was added phosphorus trichloride (0.76 ml) at ambient temperature. The mixture was refluxed for 1 hour, and cooled. The mixture was adjusted to pH 7.8 with aqueous sodium carbonate. The organic layer was separated, washed with brine, dried over magnesium sulfate, and evaporated. The residue was triturated with diisopropyl ether to give 2-(3,4-dimethoxyphenyl)-4-methyl-5-(3-pyridyl)imidazole (0.39 g).
