实验过程

The 4-acetyl-pyridine N-oxide used is prepared in the following manner: 11.0 ml (100 mmol) of 4-acetyl-pyridine and 31.3 g (100 mmol) of 55% m-chloro-perbenzoic acid are boiled under RF for 16 h in 200 ml of methylene chloride. Precipitation with 200 ml of diethyl ether gives 4-acetyl-pyridine N-oxide; m.p. 132°-133°.
