Versuchsvorschrift
A mixture of 4-(4-methoxyphenyl)-2-methylpyridine (375 mg) and metachloroperbenzoic acid (70%, 695 mg) in chloroform is stirred at room temperature for two hours. Concentration and purification over silica gel (eluent dichloromethane/methanol from 100/0 to 90/10) affords 384 mg of 4-(4-methoxyphenyl)-2-methylpyridine 1-oxide as an orange oil used without further purification.
