Participants

Reaction Steps

Diethyl(2-(((6-bromopyridin-3-yl)amino)methylene)malonate (36 g, 0.105 mol) was added to boiling diphenyl ether (185 mL) in batches over 5 min, and reacted under reflux for 45 min. After confirming a disappearance of the raw materials by a thin layer chromatography plate (ethyl acetate:petroleum ether=1:3), cooled and poured into petroleum ether to precipitate a solid. The reaction mixture was suction filtered to give 17.1 g of a khaki solid.
