tert-Butyl 2-(2-pyridyl)ethylcarbamate (18.5 g, 83 mmol) and 3-chloroperbenzoic acid (77%, 24.5 g, 109 mmol) were dissolved in ethyl acetate (200 ml), and the mixture was stirred at room temperature for 15 hrs. The solvent was evaporated, and the residue was subjected to a silica gel column chromatography. The fractions eluted with methanol-ethyl acetate (1:4, v/v) were collected and concentrated to give the titled compound (19.6 g, 99%).
