실험 절차

15 g (0.06 mol) of 2-amino-1-(4-chlorophenyl)-3-cyano-4,5-dimethylpyrrole in 100 ml of formamide, 30 ml of dimethylformamide and 15 ml of concentrated formic acid are heated under reflux for 7 hours. The crystals which precipitate on cooling are washed with water and recrystallised from ethanolic potassium hydroxide solution. Melting point: 250° C., yield: 13 g (79% of theory).
