Imidazole → HCID 57323911, compound

Participants

Reaction Steps

To a suspension of 4.08 g of imidazole and 30 ml of dry methylene chloride, 1.78 g of thionyl chloride was added with ice-cooling. The resultant mixture was stirred for 30 minutes, followed by an addition of 2.10 g of 2-phenylthio-2'-hydroxyacetophenone. The thus-obtained mixture was stirred at room temperature for 2 hours. Ice water was then added to the reaction mixture, followed by its extraction with methylene chloride. The methylene chloride extract was then subjected to a post treatment in the same manner as in Example 10. The reaction product was separated by column chromatography, thereby obtaining 0.2 g of Isomer A (Compound 61) and 1.0 g of Isomer B (Compound 62) of 1-(2-hydroxyphenyl)-1-imidazolyl-2-phenylthioethylene as colorless crystals respectively.
