| titleOfInvention | Method of obtaining pure beta-methyldigoxine |
| abstract | A method of obtaining pure ß-methyldigoxin by methylating digoxin in a solution of dimethylformamide and a neutral solvent in the presence of barium, aluminum or strontium hydroxide, and then separation on a chromatographic column in the SiC2 / hydrogen chloride system and lower alcohol, characterized in that the reaction solution is washed away from the reaction solution. water, dimethylformamide, and then the solution in a neutral solvent, which is the medium of the reaction, is dosed onto a chromatography column characterized in that a saturated water mobile phase is passed through, the alcohol content of which changes abruptly during the separation cycle.
