Water → 2-(1-Phenylimidazol-2-yl)ethanol

Participants

Reaction Steps

1-Phenylimidazole (3.00 g) was dissolved in tetrahydrofuran. To the solution was added dropwise a solution of n-butyllithium (1.6 M) in hexane (16.9 ml) at −70° C. The mixture was stirred for 30 minutes at the same temperature, to which 50% solution (4.76 g) of ethyleneoxide in tetrahydrofuran. The mixture was warmed up to room temperature over 1 hour, and stirred 19 hours at the same temperature. To the reaction mixture was added water. The mixture was subjected to extraction with ethyl acetate. The extract was dried over anhydrous magnesium sulfate, followed by concentration under reduced pressure. The residue was subjected to column chromatography on silica gel (developing solvent: ethyl acetate-methanol 100:0→93:7) to give the title compound.
