Versuchsvorschrift

In 2.5 moles of 2,3-dicyanonaphthalene, 0.075 mole of sodium methoxide and 1 liter of methanol, an ammonia gas was flowed with a suitable flow rate for 40 minutes. Then, the reaction solution was refluxed with heating while flowing the ammonia gas for 4 hours. After cooling, the product was filtered, and recrystallized from a mixed solvent of methanol/ether to yield yellow 1,3-diiminobenz (f) isoindoline in 66% yield.
