A solution of 3-fluoro-4-nitropyridine-1-oxide (12 g) and indan-5-amine (10 g) in 200 ml ethanol was stirred at reflux for two hours, and thereafter cooled, diluted with ether and filtered to give 19 g solid, m.p. 195°. Four grams were recrystallized from ethanol to give 2.6 g crystals, m.p. 194°-195°.
