2-エチル-3-ヒドロキシ-6-メチルピリジンこはく酸塩

使用The Chinese name of Mesidol is 2-ethyl-6methyl-3-hydroxypyridine succinic acid (Mexidox), 2-ethyl-6-methyl-3-hydroxypyridine succinate (emoxypine, product Name-MEXIDOL, etc.) is widely used in medicine as an antioxidant and anti-hypoxic agent. Use 2-ethyl-6-methyl-3-hydroxypyridine succinate as a nootropic and anxiolytic, anti-ischemic and atherosclerotic, anti-angina, liver protection, antibacterial, etc.

製造方法3.5 liters of ethanol, 1.2 kg of 2-ethyl-6-methyl-3-hydroxypyridine and 1.0 kg of succinic acid were added to the reactor. The reaction mass is heated to the boiling point of ethanol (78°C) and stirring is continued for 20 minutes until the components are completely dissolved. Then, keep the reaction mass in the reactor under stirring until the temperature reaches 20°C, cool to 5°C and keep at this temperature for 16 hours, stirring occasionally. The suspension is then stirred until the material is homogeneous, overloaded in a centrifuge and filtered. The precipitate of the succinate salt of 2-ethyl-6-methyl-3-hydroxypyridine was dried to constant weight in a vacuum oven at 45°C. The yield of the target product 2-ethyl-6-methyl-3-hydroxypyridine succinate (Mexitrad) was 89%.
