実験手順

N-Benzyloxypyridinium p-toluenesulfonate was prepared by mixing pyridine-N-oxide and an equimolar amount of benzyl p-toluenesulfonate and heating the mixture at 85°C for 4 hours. The crude product was recrystallized from a mixture of ethanol and ethyl acetate. By this procedure N-benzyloxypyridinium p-toluenesulfonate having a melting point of 107° to 109°C was obtained.
