Reaction Steps

6,7-Dimethoxy-4-(4-aminophenoxy)quinoline (54 mg) and commercially available 3-thiophenecarboxylic acid (44 mg) were dissolved in N,N-dimethylformamide (2 ml), 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (82 mg) was added, and the admixture was stirred at room temperature for 31 hours. The reaction mixture was then purified in the same manner as described in Example 51 to obtain 41 mg of the title compound (yield: 55%).
