実験手順

Ethylmagnesium bromide (3.0 M solution in diethyl ether, 0.25 mL, 0.75 mmol) was added to a stirred solution of 9-chloro-1-(2-methoxy-4,6-dimethylpyrimidin-5-yl)-1,2,3,4-tetrahydropyrimido[1,2-a]benzimidazole-6-carbaldehyde (256 mg, 0.689 mmol) in tetrahydrofuran (3.5 mL) at 0° C., and the mixture was stirred at 0° C. for 30 min. The reaction was quenched by water, 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 washed with ethyl acetate/diisopropyl ether to give the title compound as a colorless powder (224 mg, 0.557 mmol, 81%).
