Steps:
1 6-Aminoquinoxaline
6-Aminoquinoxaline Glyoxal sodium bisulfite adduct (Aldrich, 14.3g, 50 mmol) was added in small portions to a solution of 1,2,4-triaminobenzene dihydrochloride (9.8 g, 50 mmol) in 200 ml of 10% by weight sodium carbonate in water. The reaction mixture was heated to 100° C. for two hours and then cooled to 0° C. The crystals formed were filtered off and dried in vacuo to give a crude yield of 7.06 g (a yield of 97%) of brown crystals. Recrystallization from benzene gave 6.32 g (a yield of 87%) yellow crystals, m.p. 157-8° C. Using various analytical procedures, these yellow crystals were determined to be 6-aminoquinoxaline.
