FIELD: chemistry.
SUBSTANCE: method of obtaining pharmacopoeia furadonina consists of dissolving technical furadonina heated to a temperature of 50±10°C dimethylformamide, followed by heating the reaction mass to a temperature of 100±5°C and held for 20÷40 minutes, the reaction mass is cooled and it was held for 1.5÷2.5 hours at 20±10°C. After soaking the paste is pressed onto a centrifuge, washed with isopropyl alcohol and purified water, and transferred to the drying which is carried out at a temperature of 65±10°C to a moisture content of not more than 7.5%.
EFFECT: increased output of beta-chlorine-L-alanine of suitable quality.
