Potassium Carbonate → 4-[1-(4-Chlorophenacyl)-1H-benzimidazol-2-yl]-furazan-3-yl-N-(3-hydroxypropyl)-amine

Participants

Reaction Steps

A suspension of 4-(1H-benzimidazol-2-yl)-furazan-3-yl-N-(3-hydroxypropyl)-amine (0.70 g, 0.27 mmol), potassium carbonate (0.472 g, 3.42 mmol) and 4-chlorophenacyl bromide (0.069 g, 0.29 mmol) in DMF (5 ml) is stirred at room temperature for 16 hours. The reaction mixture is diluted with ethyl acetate, washed with water and dried over sodium sulphate. Filtration of the sodium sulphate, concentration of the filtrate under reduced pressure and chromatography of the residue on silicagel using hexane-ethyl acetate as eluent gives the title compound as a yellowish solid, m.p. 166-169° C.
