Reaktionsschritte

1 g of 2,3-diphenylpyridine was dissolved in chloroform and 1.4 g of 70% m-chloroperoxybenzoic acid was added, followed by stirring at room temperature for 15 hours. After the reaction solution was washed with an aqueous 5% potassium carbonate solution and saturated brine, and dried over anhydrous magnesium sulfate, the solvent was evaporated under reduced pressure to obtain 1.3 g of a crude crystal. The crude crystal was washed with diisopropyl ether to obtain 922 mg of the desired compound as a colorless crystal having a melting point of 167 to 170° C.
