2-[4-(5,6,7,8-tetrahydro-quinolin-8-ylamino)-butyl]-isoindol-1,3-dione (160 mg, 0.46 mmol) and 2-chloromethyl-6-trifluoromethyl-1H-benzoimidazole (129 mg, 0.55 mmol), N,N-diisopropylethylamine (100 μL, 0.60 mmol), and potassium iodide (8 mg, 0.05 mmol) in acetonitrile were stirred at 40° C. for 3 days. Then the reaction mixture was cooled and the solvent was removed under reduced pressure to afford a red oil. Purification by flash column chromatography on silica gel using NH4OH/CH3OH/CH2Cl2 (1:2:97) afforded the product as an orange foam (190 mg, 76%). 1H NMR (CDCl3) δ 1.37-1.45 (m, 5H), 1.56-1.70 (m, 2H), 2.18-2.20 (m, 1H), 2.57-2.61 (m, 1H), 2.72-2.80 (m, 3H), 3.49-3.54 (m, 2H), 3.98-4.16 (m, 3H), 7.13-7.15 (m, 1H), 7.40-7.45 (m, 2H), 7.62-7.74 (m, 5H), 7.86 (br m, 1H), 8.62 (br m, 1H).
