Reaction Steps

To 1-naphthylamine (5.43 g) in 100 ml of absolute ethanol was added 3-fluoro-4-nitropyridine-N-oxide (6.0 g) in 25 ml of ethanol and this mixture was heated to 70° C. and stirred for six hours. The mixture was filtered to yield a solid (6.6 g) which was recrystallized from ethanol to yield a solid (2.6 g), m.p. 200°-201° C. (decomp.).
