Reaction Steps
2.0 g (0.008 mol) of 2-chloro-3-tert-butylamino-5,6-dicyanopyrazine was dissolved in 100 ml of dry N,N-dimethylformamide, and ammonia gas was blown into it under stirring at room temperature. Two hours later, the reaction solution was poured into 1 liter of water and neutralized with hydrochloric acid. The precipitated solid was collected by filtration and recrystallized from isobutyl alcohol to obtain 1.2 g of slightly yellow crystals (yield: 69.4%, melting point: at least 250° C.).
