실험 절차
To a stirred solution of 9.3 g (0.05 mol) of disodium dimercaptomethylenemalononitrile in 100 ml of dimethylformamide was gradually added 10 g (0.05 mol) of 2,3-dichloro-5,6-dicyanopyrazine in 70 ml of dimethylformamide. The reaction mixture was stirred at 40° C for 8 hours and poured into 700 ml of water. The resulting solid was collected by suction filtration, washed with water, and dried. The crude product was dissolved in acetone-CHCl3, decolorized with charcoal and dried over MgSO4. Recrystallization from CHCl3 yields 5.0 g (37%) of yellow crystals. M.p. ~280° C (dec.). νCN (cm31 1): 2220.
