Imidazole → 5-(Tert-butyldimethylsilanyloxymethyl)-pyridine-2-carbonitrile

Participants

Reaction Steps

5-(Hydroxymethyl)pyridine-2-carbonitrile (258 mg) was dissolved in dimethylformamide (8 ml), tert-butyl dimethylchlorosilane (347 mg) and imidazole (326 mg) were added, and the mixture was stirred at room temperature for 1 hr. Water (20 ml) was added and the mixture was stirred, extracted with ethyl acetate (once with 50 ml and once with 20 ml), washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated and the obtained residue was purified by column chromatography (Yamazen HI-FLASH™ COLUMN size 2 L, elution solvent: hexane/ethyl acetate) to give the title compound (405 mg).
