Versuchsvorschrift

Sodium hydride (60% in oil, 17.5 mg, 0.438 mmol) was added to a stirred solution of 2-[9-chloro-1-(2,4-dichlorophenyl)-1,2,3,4-tetrahydropyrimido[1,2-a]benzimidazol-6-yl]propan-2-ol (150 mg, 0.365 mmol) in N,N-dimethylformamide (1.5 mL) at room temperature. After stirring 5 min, methyl iodide (77.7 mg, 0.548 mmol) was added to the mixture, and the mixture was stirred at room temperature for 4 hr. The mixture was diluted with water, 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 10-40% ethyl acetate/n-hexane gradient mixture. The filtrate was concentrated in vacuo to give the solid, which was recrystallized from ethyl acetate/diisopropyl ether to give the title compound as a colorless crystal (133 mg, 0.313 mmol, 86%).
