Diethyl Ether → 1H-Imidazole-1-ethanol, 5-((3,5-dichlorophenyl)thio)-4-(1-methylethyl)-2-(3-(phenylmethoxy)propyl)-

Participants

Reaction Steps

In 30 ml of dry diethyl ether was dissolved 3.0 g (5.8 mmol) of the ester (130d), to the mixture was added 220 mg (5.8 mmol) of lithium aluminium hydride under ice-cooling. The mixture was stirred at room temperature for 15 minutes. The reaction mixture was diluted with water and extracted with ethyl acetate. The extract was washed with water, dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate), and further recrystallized from n-hexane to provide 2.4 g (yield 87%) of 2-(2-(3-benzyloxypropyl)-5-(3,5-dichlorophenylthio)-4-isopropyl-1H-imidazol-1-yl)-ethanol (136e) as crystals. mp 104-106° C.
