EXAMPLE 143
4-Chloro-3-cyano-2-dimethylformamidino-5-formyl-1-methylpyrrole
364 ml of phosphoryl chloride (POCl.sub.3) were added dropwise at 0.degree. to 5.degree. C. to 1.5 1 of DMF. After one hour at 0.degree. to 5.degree. C., a solution of 137 g of 2-amino-3-cyano-1-methylpyrrolin-4-one (Example 1) in 1.5 1 of DMF was added dropwise to the reaction mixture (exothermic reaction with temperature rising to 40.degree. C.). After the mixture had been stirred at 100.degree. C. for 4 hours, it was cooled to room temperature, hydrolyzed with 5 l of water and adjusted to pH 8 to 9 with 50% concentrated sodium hydroxide solution. The beige-colored precipitate was filtered off with suction and dried in an oven at 50.degree. C. 180 g (75% of theory) of the compound of the formula ##STR40## of melting point 150.degree. to 152.degree. C. were obtained. The IR, NMR, UV and mass spectra and the elemental analysis are consistent with the structural formula.

4-Bromo-3-cyano-2-dimethylformamidino-5-formyl-1-methylpyrrole
172 g of phosphoryl bromide (POBr.sub.3) were added dropwise at 0.degree. to 10.degree. C. to 200 ml of DMF. The mixture was stirred for 5 minutes and then a further 100 ml of DMF were added. 27.4 g of 2-amino-3-cyano-1-methylpyrrolin-4-one (Example 1) were introduced a little at a time into the cooled mixture. After the exothermic reaction had subsided, the reaction solution was stirred at 70.degree. C. for 2 hours and then poured into 2 kg of ice-water. The suspension was stirred at room temperature for 8 hours. The precipitate was then filtered off with suction, washed and dried in an oven at 50.degree. C. 12.6 g (22%) of the compound of the formula ##STR41## of melting point 180.degree. to 184.degree. C. were obtained. The IR, NMR, UV and mass spectra and the elemental analysis are consistent with the structural formula.

EXAMPLE 345
2-Amino-4-chloro-3-cyano-5-formyl-1-methylpyrrole
84.8 g of 4-chloro-3-cyano-2-dimethylformamidino-5-formyl-1-methylpyrrole (Example 143) were dissolved in 50 ml of water and 150 ml of ethanol. To this was added a solution of 15 g of KOH in 150 ml of ethanol, and the mixture was refluxed for 10 minutes. It was then poured into 1 kg of ice-water, the pH was adjusted to 7 with concentrated formic acid, and the precipitate was filtered off with suction, washed and dried in an oven at 50.degree. C. 60.2 g (92% of theory) of the compound of the formula ##STR46## of melting point 282.degree. to 285.degree. C. are obtained. The IR, NMR, UV and mass spectra and the elemental analysis are consistent with the structural formula.

The mixture was cooled to room temperature and then diluted with H.sub.2 O, and the precipitate was filtered off with suction. 4.2 g (83% of theory) of the compound of the formula ##STR58## of melting point >260.degree. C. were obtained. The IR, NMR, UV and mass spectra and the elemental analysis are consistent with the structural formula.
