Reaction Steps
A mixture of 2-(5-chlorothiophen-2-yl)-4-(3-pyridyl) imidazole (1.07 g), 35% formalin aqueous solution (35 ml), potassium carbonate (1.70 g), isopropanol (30 ml) and N,N-dimethyl-formamide (10 ml) was stirred at 90° C. for 2 hours. After cooling, water was added to the mixture and precipitated solid was collected by filtration. The solid was dissolved in methanol and, after removing insolubles by filtration, the solvent was removed under reduced pressure. The resulting residue was triturated with ethyl acetate to obtain 2-(5-chlorothiophen-2-yl)-5-hydroxymethyl-4-(3-pyridyl)imidazole (519 mg) as colorless powder.
