Triethylamine → HCID 22662877, compound

Participants

Reaction Steps

4-(Hydroxymethyl)-5-methyl-1H-imidazole (4 g, 26.9 mmol) was dissolved in DMF (80 mL). Triethylamine (13.5 mL, 96.9 mmol) and tert-butyl(dimethyl)silyl chloride (4.68 g, 31.0 mmol) were added, followed by stirring for three hours. Ethyl acetate was added to the reaction solution, and the organic layer was washed with brine and dried over anhydrous sodium sulfate. Following concentration under reduced pressure, the residue was purified by silica gel column chromatography (elution solvent: hexane/ethyl acetate=4/1, dichloromethane/methanol=92/8) to obtain 4.67 g of the title compound (77%).
