실험 절차

To a solution of ethyl 1-(4-fluorophenyl)-2-(((2,3,6-trifluorophenyl)amino)methyl)-1H-imidazole-5-carboxylate (23) (56 mg, 0.14 mmol) in DMF (2 mL) was added sodium hydride (60% in mineral oil, 7 mg, 0.28 mmol) and stirred for 30 minutes. To the solution was added methyl iodide (18 μL, 0.28 mmol) and again stirred overnight at room temperature. Ethyl acetate was added and the reaction was acidified with 2N HCl. The ethyl acetate was separated and the aqueous layer was extracted again with ethyl acetate. The combined organic layers were dried over sodium sulfate, filtered and concentrated in vacuo to give 1-(4-fluorophenyl)-2-((methyl(2,3,6-trifluorophenyl)amino)methyl)-1H-imidazole-5-carboxylic acid (24).
