実験手順

To a cooled (0° C.) solution of 1.53 g (8.47 mmol) of methyl 6,7-dihydro-5H-cyclopenta[b]pyridine-7-carboxylate from step A above in 30 mL of dichloromethane was added 1.61 g (9.31 mmol) of m-CPBA. The solution was allowed to stir for 1 h and then quenched with 50 mL of a saturated aqueous sodium bicarbonate solution. The layers were separated and the aqueous phase extracted with dichloromethane (3×50 mL). The combined organic extracts were washed with brine, dried over magnesium sulfate, filtered and evaporated in vacuo to yield the title compound as a light brown solid that was used without purification. LC-MS: m/z (E/S) 194.2 (MH)+.
