Versuchsvorschrift

To a solution of 5-furan-2-yl-isoxazole-3-carboxylic acid (7 mg) and 3-imidazol-1-yl-propyl amine (0.005 mL) in DMF was added 8 mg of HOBt, 9 mg of EDC and 0.014 mL of TEA. After stirring at room temperature for 18 hrs, the reaction solution was concentrated in vacuo. The obtained concentrate was purified by preparative HPLC to afford 4 mg of 5-furan-2-yl-isoxazole-3-carboxylic acid (3-imidazol-1-yl-propyl)-amide (Yield: 35%).
