Versuchsvorschrift

A solution of 2-aminocarbonylamino-5-(2-naphthyl)pyrrole-3-carboxamide (Compound No. 1-1, 92 mg, 0.31 mmol) and N-chlorosuccinimide (46 mg, 0.34 mmol) in anhydrous N,N-dimethylformamide (2 mL) was stirred at 60° C. for 2 hours. After cooling, water (10 mL) was added thereto, the precipitated solid was filtered off, and washed with water (10 mL) and acetone (10 mL). The obtained solid was dried at 50° C. under reduced pressure to give the target compound (46 mg) as a pale brown solid (Yield 45%).
