실험 절차
m-Chloroperbenzoic acid (7.3 g) in dichloromethane (100 ml) was added dropwise to a stirred solution of 4 -piperidino-5 -bromo-2 -picoline. After 16 hours, the solution was washed with 10 % aqueous sodium carbonate, dried (K2CO3) and stripped. The residue was chromatographed (silica gel, chloroform:methanol) to give 4 -piperidino-5 -bromo-2 -picoline-N-oxide, 6.79 g, m.p. 115°-6 ° from ether.
