Reaction Steps

A solution of 100 mg (0.220 mmol) 6-(4-Bromo-butoxy)-3-(4-bromo-phenyl)-2-methyl-benzo[b]thiophene (example 27.5), 0.024 g (0.35 mmol) of imidazole and 0.0144 g (0.330 mmol) sodium hydride (55% suspension in oil) in 0.5 ml of N,N-dimethylformamide was stirred for 1 hour at room temperature. The reaction mixture was then poured into 30 ml of ice-water and extracted 3 times with 10 ml of ether. The combined ether phases were washed with brine, dried over magnesium sulfate and evaporated under reduced pressure. The residue formed was chromatographed on silica gel with a 9:1 v/v mixture of dichloromethane and methanol as the eluent yielding 84.2 mg (86.7%) 1-{4-[3-(4-Bromo-phenyl)-2-methyl-benzo[b]thiophen-6-yloxy]-butyl}-1H-imidazole as colorless oil, MS: 441 (MH+, 1Br).
