Procedure
To a stirred suspension of 3-(3-hydroxymethylpyridin-2-yl)-nitrobenzene hydrobromide (0.3 g) and imidazole (106 mg) in N,N-dimethylformamide (3 ml) was added tert-butyldimethylsilyl chloride (216 mg), and the mixture was stirred for 18 hours. The mixture was diluted with ethyl acetate and washed with a saturated aqueous sodium hydrogencarbonate solution and brine. The separated organic layer was dried over sodium sulfate and evaporated under reduced pressure to give 3-(3-tert-butyldimethylsilyloxymethylpyridin-2-yl)nitrobenzene (438 mg).
