실험 절차

To a solution of methyl 8-chloro-1-(2,4-dichlorophenyl)-2,3-dihydro-1H-imidazo[1,2-a]benzimidazole-5-carboxylate (100 mg, 0.25 mmol) in tetrahydrofuran (2.5 mL) was added a solution of cyclopropyl magnesium bromide in tetrahydrofuran (1.0 M, 1.5 mL, 1.5 mmol) at 0° C. The mixture was stirred at 60° C. for 1.5 hr. Water was added to the reaction mixture at room temperature and the mixture was extracted with ethyl acetate. Organic layer was washed with brine, dried over anhydrous magnesium sulfate and concentrated in vacuo. The residue was passed through the silica gel pad eluting with ethyl acetate and recrystallized from ethyl acetate to give the title compound (64.4 mg, 0.144 mmol, 57%) as colorless crystals.
