Procedure
1.15 g (50 mmol) of sodium were dissolved in 100 ml of anhydrous methanol, and after that 7.4 g (40 mmol) of 3-methoxy-2-methyl-6-nitropyridine N-oxide were added at 20° C. and while stirring. The mixture was then heated to reflux for 3 h and, after having been cooled down, concentrated in vacuo; the residue was taken up in water and this mixture was extracted with dichloromethane; the organic phase was dried and concentrated and the residue was crystallized using diisopropyl ether. 7 g of product were obtained, m.p. 63°-65° C.
