Reaction Steps

50 mg (0.35 mmol) 3-amino-2-aminocarbonyl-thiophene is covered with urea. The urea is heated until molten. After 5 minutes of heating, the molten mixture is poured into 1 N NaOH (2 mL). Acetic acid is added to neutralize the mixture (pH 7) and the resulting white precipitate is collected. Yield: 39 mg (0.23 mmol, 66%).
