実験手順
tert-Butyl (E)-3-(2-pyridyl)-2-propenoate (2.05 g, 10.0 mmol) was dissolved in ethyl acetate (10 ml), and 3-chloroperbenzoic acid (ca. 70%, 2.35 g, 10.5 mmol) was added thereto. The mixture was stirred at room temperature overnight. The reaction mixture was subjected to a silica gel (100 g) column chromatography. The fractions eluted with ethyl acetate-ethanol (5:1, v/v) were collected and concentrated to give the title compound (2.14 g, 96%).
