Reaktionsschritte

39 g (0.16 mol) 3-chloroperbenzoic acid in 450 mL DCM (dried on sodium sulphate) were added dropwise within 2 h to 25 g (0.15 mol) 5-bromo-2-methylpyridine in 50 mL DCM. Then the reaction mixture was stirred for 20 h at RT and extracted with 15% potassium carbonate solution. The organic phase was dried on sodium sulphate and evaporated down.
