Trityl chloride → 4-iodo-2-methyl-1-trityl-1H-imidazole

Participants

Reaction Steps

Triethylamine (13.4 mL, 96.2 mmol) followed by trityl chloride (20.1 g, 72.1 mmol) were added to an ambient temperature solution of 4-iodo-2-methyl-1H-imidazole (ca. 10 g, 48.1 mmol) in methylene chloride (90 mL). After stirring at ambient temperature for 2 days, the reaction mixture was diluted with methylene chloride and washed with water and brine, dried (sodium sulfate) and concentrated in vacuo. Chromatography over silica eluting with 0-15% acetone/methylene chloride afforded the title compound.
