실험 절차
tert-Butyl 2-pyridinecarboxylate (14.0 g, 78 mmol) was dissolved in ethyl acetate (200 ml), and 3-chloroperbenzoic acid (ca. 77%, 26.2 g, 117 mmol) was added thereto. The reaction mixture was stirred at room temperature for 40 hrs. The solvent was evaporated under reduced pressure. The residue was subjected to a silica gel column chromatography and eluted with ethyl acetate-acetone (1:1, v/v) to give the titled compound (12.4 g, 81%).
