Procedure

A solution of 20 g 4-pyridylcarbinol, 28.9 g of chloro-tert-butyl-dimethylsilane and 14.4 g imidazole in 200 ml dimethylformamide is stirred 3 hours at room temperature. Product is isolated by extraction into ethyl acetate/hexane (1:1) and washing extract 4 times with 400 ml of water. The solution is filtered through silica gel and concentrated in vacuo to yield 4-(tert-butyl-dimethylsilyloxymethyl)pyridine.
