反応手順
A solution of 5 g of 3-fluoro-4-nitropyridine-N-oxide (disclosed in Talik and Talik, Roczniki Chemii, 38, 777 (1964)) and 5 g of 1-aminopyrrole in 75 ml of ethanol was stirred one hour at 85° and thereafter cooled and filtered to give 6 g of 4-nitro-N-(1H-pyrrol-1-yl)-3-pyridinamine-N-oxide as a solid, d 224°-226°. A 3 g sample was recrystallized from ethanol to give 2 g of crystals, d 224°-226°.
