실험 절차

Benzoyl isothiocyanate (0.034 g, 0.2 mmol) was added to a solution of 4-bromo-3-(isobutylamino)-1H-pyrrole-2-carboxylic acid ethyl ester (0.050 g, 0.17 mmol) in CH2Cl2 and the resulting mixture was stirred at r.t. for 1 h before it was concentrated in vacuo. The residue was dissolved in ammonia (7M in methanol, 1.5 mL) and stirred at 70° C. for 4 h. Additional ammonia (7M in methanol, 1 mL) was added and the mixture was stirred at 80° C. for 5 h. The mixture was cooled to r.t. and the precipitated product was filtered and washed with diethyl ether. After recrystallization with methanol the title compound (0.028 g, 55%) was obtained as a white solid.
