Participants

Reaction Steps

To a tetrahydrofuran solution of Grignard reagent prepared from 73 mg of magnesium and 369 mg of n-propyl bromide, 202 mg of 1-(2-hydroxyphenacyl) imidazole (II) was added dropwise under ice-cooled conditions while stirring, and the mixture was refluxed for 2 hours. After ice-cooling, an aqueous solution of ammonium chloride was added to the mixture to decompose the surplus amount of the Grignard reagent and addition salts produced in the reaction. Extraction with chloroform was performed on this mixture and the chloroform layer was washed with water, followed by drying over anhydrous magnesium sulfate. The extract thus obtained was purified by means of silica gel column chromatography (eluent: chloroform) to produce 70 mg of the title compound at a yield of 29%.
