FIELD: medicine, pharmaceutics.
SUBSTANCE: invention relates to method of obtaining phosphonomethyl-substituted phthalocyanines, which consists in interaction of chlormethyl-substituted phthalocyanons with phosphorylating agent - phosphorus trichloride with the following hydrolysis of reaction product in water, water-alkaline or acid-mixture solution. Interaction is carried out in presence of aluminium chloride and tertiary amine at temperature 70-80°C for 2-20 hours.
EFFECT: method ensures increase phosphorylation safety and increased yield of phosphonomethyl-substituted phthalocyanines.
