Procedure

To a solution of 1891 mg of (6-methyl-1-oxidopyridin-3-yl)methyl benzoate in 38 ml of DMF was added 11 ml of trifluoroacetic anhydride, followed by stirring at room temperature overnight. After evaporating trifluoroacetic anhydride under reduced pressure, a saturated aqueous sodium hydrogen carbonate solution was added thereto, followed by extraction with chloroform. The organic layer was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: chloroform-methanol) to obtain 3.675 g of [6-(hydroxymethyl)pyridin-3-yl]methyl benzoate.
