실험 절차
To a suspension of 3-amino-5-phenylselenophene-2-carbonitrile (4.0 g) in aqueous sodium hydroxide solution (120 mL, 10%) was added ethanol (50 mL) and the mixture refluxed for 45 min. The mixture was allowed to rt and the crystals separated were filtered off, washed with cold water and dried to give the product as golden yellow color solid (2.8 g, 67%), mp 184-186° C. 1H NMR (400 MHz, CDCl3): δ 7.50-7.53 (2H, m, Ar—H), 7.36-7.38 (3H, m, Ar—H), 7.04 (1H, s, H-4), 5.84 (2H, br s, —CONH2), 5.12 (2H, br s, —NH2).
