실험 절차

Sodium hydride (60% in oil, 27.1 mg, 0.678 mmol) was added to a stirred solution of 1-{9-chloro-1-[6-(dimethylamino)-4-methylpyridin-3-yl]-1,2,3,4-tetrahydropyrimido[1,2-a]benzimidazol-6-yl}propan-1-ol (226 mg, 0.565 mmol) in N,N-dimethylformamide (5.0 mL) at room temperature. After stirring 5 min, ethyl iodide (132 mg, 0.848 mmol) was added to the mixture, and the mixture was stirred at room temperature for 6 hr. The mixture was diluted with aqueous saturated ammonium chloride, and extracted with ethyl acetate. The combined organic layer was washed with brine, dried over anhydrous magnesium sulfate, filtered, and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel eluting with a 50-100% ethyl acetate/n-hexane gradient mixture. The filtrate was concentrated in vacuo to give the solid, which was recrystallized from ethyl acetate to give the title compound as a colorless crystal (121 mg, 0.283 mmol, 50%).
