실험 절차

21.2 g (0.21 mole) of triethylamine were first added to a suspension of 39.6 g (0.2 mole) of 2-amino-3-aminocarbonyl-4-tert.-butyl-thiophene in 300 ml of toluene, and 16.5 g (0.21 mole) of acetyl chloride were then added dropwise. After the exothermic reaction had ended, the mixture was worked up by filtering off the solid product and washing it with water. 38.6 g of 2-acetylamino-3-aminocarbonyl-4-tert.-butyl-thiophene of melting point 251° C. were obtained in this manner.
