Imidazole → 3-(Tertbutyldimethylsilyloxy)-1-(1,2,4-triazol-1-yl)propane

Participants

Reaction Steps

To a solution of 3-(1,2,4-triazol-1-yl)propan-1-ol (7 g, 55 mmol) in DMF (70 ml) was added tertbutyldimethylsilyl chloride (9.1 g, 60 mmol) followed by DMAP (336 mg, 2.7 mmol) followed by imidazole (4.5gr, 66 mmol). After stirring overnight at ambient temperature, the volatiles were removed under vacuum and the residue was partitioned between water and ethyl acetate/ether. The organic layer was separated, washed with water, brine, dried (MgSO4) and evaporated. The residue was purified by column chromatography eluting with methylene chloride/ether (6/4) to give 3-(tertbutyldimethylsilyloxy)-1-(1,2,4-triazol-1-yl)propane (11.1 gr, 84%).
