Reaction Steps

To a solution of 2-{3-[1-(1-Benzyl-5-bromo-1H-benzimidazol-2-yl)-2-methyl-propylamino]-propyl}-isoindole-1,3-dione (260 mg, 0.56 mmol) and triethylamine (0.47 ml, 3.36 mmol) in DCM (3 ml) at 0° C., was added 4-chlorobenzoylchloride (0.36 ml, 2.8 mmol, 5 eq). The reaction mixture was stirred at 0° C. for 30 minutes. Ethyl acetate and saturated sodium bicarbonate were added. The mixture was extracted with ethyl acetate. The organic layers was combined, dried over MgSO4, filtered, and the filtrate was concentrated in vacuo. The crude material was purified by flash chromatography to give N-[1-(1-Benzyl-1H-benzimidazol-2-yl)-2-methyl-propyl]-N-[3-(1,3-dioxo-1,3-dihydro-isoindol-2-yl)-propyl]-4-chloro benzamide (182 mg, yield 54%)
