Reaction Conditions

Reaction Steps

4-(3-Bromo-propoxy)-3-methyl-benzofuran-2-carboxylic acid (2-cyclohexyl-ethyl)-amide (100 mg) and 3-picolyl amine (250 μl) were dissolved in 1-methylpyrrolidone (2 ml) and heated at 100° C. for two hours. The reaction mixture was dissolved in ethyl acetate and washed with saturated ammonium chloride solution and water. The organic solvent was dried over anhydrous sodium sulfate and evaporated to dryness. The residue was purified by silica gel column chromatography (dichloromethane-MeOH) to afford 3-methyl-4-{3-[(pyridin-3-ylmethyl)-amino]-propoxy}-benzofuran-2-carboxylic acid (2-cyclohexyl-ethyl)-amide.
