実験手順

(1-Quinolin-4-yl-ethanone (43 mg, 0.25 mmol) and 2-(4-amino-3-formyl-phenyl)-1-cyclohexyl-1H-benzoimidazole-5-carboxylic acid ethyl ester (98 mg, 0.25 mmol) were dissolved in 500 μL ethanol and 500 μL 10% ethanolic KOH were then added. The reaction was stirred at 75° C. overnight. The reaction was acidified with 4N hydrochloric acid, extracted three times with ethyl acetate, and the organic extracts were dried with sodium sulfate and then evaporated. Purification via reverse-phase HPLC gave 24 mg product.
