実験手順

Ethylmagnesium bromide (3.0 M solution in diethyl ether, 0.23 mL, 0.69 mmol) was added to a stirred solution of 9-chloro-1-(6-methoxy-4-methylpyridin-3-yl)-1,2,3,4-tetrahydropyrimido[1,2-a]benzimidazole-6-carbaldehyde (207 mg, 0.580 mmol) in tetrahydrofuran (5.0 mL) at 0° C., and the mixture was stirred at room temperature for 3 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 washed with diisopropyl ether to give the title compound as a colorless powder (141 mg, 0.364 mmol, 63%).
