Pyrindan → 6,7-Dihydro-5H-cyclopenta[b]pyridine 1-oxide

참여 물질

반응 단계

mCPBA (10.0 g, 44.6 mmol) was added slowly to a mixture of 6,7-dihydro-5H-cyclopenta[b]pyridine (from Aldrich, 5.0 g, 42 mmol) in DCM (50 mL). The reaction mixture was stirred at room temperature for 2 h. The solution was then washed with aq. Na2S2O3 (50 mL) and 1 M NaOH (50 mL). The aqueous layer was extracted with DCM (5×70 mL). The combined organic layers were dried, filtered and concentrated under reduced pressure to give the sub-title compound (4.5 g, 79%). LCMS calc. for C8H10NO (M+H)+: m/z=136.1. Found: 136.2.
