実験手順

Sodium hydride (60% in oil, 52.4 mg, 1.31 mmol) was added to a stirred solution of {9-chloro-1-[4-chloro-2-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimido[1,2-a]benzimidazol-6-yl}(cyclopropyl)methanol (500 mg, 1.09 mmol) in N,N-dimethylformamide (4.0 mL) at room temperature. After stirring 5 min, methyl iodide (232 mg, 1.64 mmol) was added to the mixture, and the mixture was stirred at room temperature for 3 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 recrystallized from ethyl acetate/n-hexane to give the title compound as a colorless crystal (396 mg, 0.842 mmol, 77%).
