Beschreibung
Zusammenfassung:	FIELD: chemical industry, organic chemistry, chemical technology. ^ SUBSTANCE: invention relates to a method for synthesis of tetrapyrrole macroheterocyclic compounds. Method for synthesis of tetrapyrazino-porphyrazine is carried out by heating 2,3-dicyanopyrazine to temperature 210-220°C and keeping the formed melt at this temperature for 25-35 min. Invention provides the simultaneous simplifying and improvement of economy indices of the method due to diminishing number of technological procedures and enhancing yield of the end product by 1.14-fold. ^ EFFECT: improved preparing method. ^ 1 tbl
