実験手順

Cyclopropylmagnesium bromide (1.0 M solution in tetrahydrofuran, 0.33 mL, 0.33 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 (111 mg, 0.299 mmol) in tetrahydrofuran (1.5 mL) at 0° C., and the mixture was stirred at 0° C. for 2 hr. 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 to give [9-chloro-1-(2-methoxy-4,6-dimethylpyrimidin-5-yl)-1,2,3,4-tetrahydropyrimido[1,2-a]benzimidazol-6-yl](cyclopropyl)methanol (155 mg).
