Sodium hydride → HCID 58355120, compound

Participants

Reaction Steps

4,5,6,7-Tetrahydro-1H-benzimidazole (2.45 g) was dissolved in DMF (20 ml), sodium hydride (60% in oil, 880 mg) was added, and the mixture was stirred at room temperature for min. 4-Methoxybutyl methanesulfonate (1.28 g) was added, and the mixture was stirred at room temperature for 15 hr. The reaction mixture was concentrated under reduced pressure, water was added and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was subjected to silica gel column chromatography, and a fraction eluted with ethyl acetate was concentrated under reduced pressure to give the object product (2.90 g).
