반응 단계

A solution of 5-bromo-2-methylpyridine (10 g, 58.13 mmol) and meta-chloroperbenzoic acid (mCPBA, 30 g, 174.39 mmol) in CHCl3 (160 mL) was heated at 60° C. for 16 h. The mixture was cooled to rt and neutralized with satd. NaHCO3. The resulting mixture was extracted with DCM. The organic layers were combined and washed with brine and dried (MgSO4).
