실험 절차
A mixture of 2.5 g 4-benzoylpyridine N-oxide m.p. 127°-30° C. (obtained according to T. KATO et. al., Yakugaku Zasshi 86, 1022-26, 1966), and 6 ml phosphorus oxychloride is refluxed for 2 hrs. After cooling, the reaction mixture is very slowly added to ice:water, basified (10N NaOH) and extracted with methylene chloride. The organic layer is washed with water, dried and solvent removed in a rotary evaporator. Yield: 2.4 g of title product, identical with that described in Ex. 4.
