実験手順

To a flask was added N1-(6-chloro-1,2,3,4-tetrahydro-acridin-9-yl)-propane-1,3-diamine (116 mg, 0.40 mmoL), 7,8-dihydro-1H,6H-quinoline-2,5-dione (85 mg, 0.52 mmoL), benzene (4 mL) and one drop of acetic acid, and the resulting mixture as heated to reflux under nitrogen. The water generated from the reaction was removed by Dean-Stark apparatus. After refluxing for 24 h, the benzene was distilled off and methanol (2 mL) was added, followed by sodium borohydride (30 mg, 0.80 mmoL). After stiring at room temperature for 24 h, the reaction was stopped and concentrated. The mixture was treated with saturated sodium bicarbonate and methylene chloride. The layers were separated and the aqueous layer was extracted with methylene chloride twice. The combined methylene chloride extract was combined, dried over sodium sulfate, filtered and concentrated. The resulting residue was purified by preparative TLC using 15% MeOH/1% ammonium hydroxide in methylene chloride to give the desired product (102 mg, 0.23 mmoL, 58%).
