Acetic Acid → HCID 54460378, compound

Participants

Reaction Steps

In ethanol (6 ml)was dissolved 220 mg (0.59 mmol)of [5-(3,5-dichlorophenylthio)-4-isopropyl-1-methyl-1H-imidazol-2-ylmethoxy]acetaldehyde (24a), followed by addition of 45 mg (1.2 mmol)of sodium borohydride, and the mixture was stirred for 15 minutes. The reaction mixture was weakly acidified with acetic acid. A saturated aqueous sodium hydrogen carbonate solution was added to neutralize again, and the mixture was extracted with methylene chloride. The extract was washed with water and dried over sodium sulfate. The solvent was distilled off under reduced pressure, and the residue was fractionated by silica gel chromatography (ethyl acetate). The product was recrystallized from n-hexane to give 144 mg of 2-{[5-(3,5-dichlorophenylthio)-4-isopropyl-1-methyl-1H-imidazol-2-yl]methoxy}ethanol (25a)(yield 65%). mp 89-90° C.
