YieldReaction ConditionsOperation in experiment
56% With selenium(IV) oxide; In ethanol; water; at 20℃; for 0.25h; To a solution of 1 g (5.0 mmol) of 1 ,2,3-triaminobenzene dihydrochloride X-6c in water (1 0ml) was added a solution of Se02 (555 mg, 5.0 mmol) in water (15 ml) at room20 temperature. After the addition was finished the reaction mixture was stirred for 15 minand then alkalized with a 30percent aq. NaOH solution while cooling on an ice bath. Theresulting orange needles were filtered off under reduced pressure, washed with water anddried. Additional purification by column chromatography (eluent: pure dichloromethane)yielded 560 mg of 4-amino-2, 1 ,3-benzoselenodiazole.25 Yield: 56percent.1H NMR (600 MHz, DMSO-d5) o: 7.26 (dd, J = 8.9, 7.2 Hz, 1 H), 6.93 (d, J = 8.8 Hz, 1 H),6.35 (d, J = 7.3 Hz, 1 H), 5.98 (s, 2H, NH2).Purity> 95 percent, calculated from 1H NMR data.
