実験手順
Cyclopropylmagnesium bromide (1.0 M solution in tetrahydrofuran, 2.9 mL, 2.9 mmol) was added to a stirred solution of 9-chloro-1-[4-chloro-2-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimido[1,2-a]benzimidazole-6-carbaldehyde (1.00 g, 2.41 mmol) in tetrahydrofuran (10 mL) at 0° C., and the mixture was stirred at room temperature for 1 hr. The reaction was quenched by aqueous saturated ammonium chloride, and the mixture was 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 to give the title compound as a colorless crystal (567 mg, 1.24 mmol, 51%).
