反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 3-chloroperbenzoic acid (19 g) was added portionwise to an ice-cold solution of 2-phenylpyridine (10 g) in DCM (30 ml). The mixture was allowed to warm to RT and was stirred at RT for 4 h. 100 ml of a NaHCO3 solution were added to the reaction mixture and the phases were separated. The aq. phase was further extracted with DCM and the combined org. phases were washed with an aq. NaHSO3 (40%) solution and evaporated off. Recrystallisation (EA) afforded 8.77 g of the desired compound. the phases were separated The aq. phase was further extracted with DCM phases were washed with an aq. NaHSO3 (40%) solution evaporated off Recrystallisation (EA)

実験手順: The N-oxide was prepared by modifying the method outlined by Zhang et al.25 using 2-phenylpyridine (5.00 g, 32.2 mmol) and 30% H2O2 in glacial acetic acid to yield the title compound as a light yellow solid (4.00 g, 72%), m.p. 154-157° C. (lit.26 m.p. 155-155.5° C.). The spectral data were consistent with literature data.27 The N-oxide was prepared
