Reaction Steps

A solution of 3-fluoro-4-nitro-pyridine-N-oxide (5 g) and 1H-indol-1-amine (4.2 g) in 25 ml of ethanol was stirred four hours at reflux. The solution was cooled and the product collected and dried to give 4 g of solid, d 195°. This material was recrystallized from ethanol/ether to give 2.2 g of solid, d 200°-201°.
