Participants

Reaction Steps

To a solution of (1H-1,2,3-triazol-4-yl)methanol (30 g, 200 mmol) in DCM (160 mL) was added imidazole (20.4 g, 300 mmol) followed by TBDMS-Cl (33.3 g, 220 mmol) as a solid in portions. After stirring at rt for 16 h, the reaction mixture was filtered through celite, and the filtrate was concentrated in vacuo. The residue was dissolved in EtOAc (500 mL) and washed with water, brine, dried over Na2SO4, and concentrated in vacuo. The crude residue was purified via silica gel chromatography (EtOAc-hexanes, 5-30%) to afford the title compound (30.2 g, 71%) as a pale yellow solid.
