Procedure

To a stirred mixture of 2-bromo-5-hydroxymethylpyridine (4.7 g, 0.023 mol) and triethylamine (3.4 mL, 0.024 mol) in DMF (30 mL) was added tert-butyldimethylsilyl chloride. After 1 h, the mixture was diluted with ether and washed with water. The ether phase was dried (MgSO4) and concentrated to give 6.8 g (97%) of product as a colorless oil.
