実験手順

tert-Butyldimethylsilylchloride (2.83 g, 18.76 mmol) was added to a suspension of 4-hydroxymethyl-1-triphenylmethylimidazole (5.80 g, 17.05 mmol) in DMF (200 mL) containing imidazole (3.48 g, 51.1 mmol). After 15 min, a clear colorless solution was obtained which was stirred at room temperature. When reaction was complete, the DMF was removed in vacuo and the residue patitioned between ethyl acetate and water. The organic phase was washed with water, saturated brine, and dried over magnesium sulfate. The title compound was obtained as a clear gum.
