| titleOfInvention | A kind of preparation method of doxylamine succinate |
| abstract | The present invention relates to a kind of preparation method of doxylamine succinate, first the Grignard reagent of selecting iodobenzene and magnesium to generate reacts with 2-acetylpyridine and generates 2-pyridine radicals phenylmethylcarbinol, through recrystallization purifying, then 2-pyridine radicals phenylmethylcarbinol is successively with Sodamide and the reaction of 2-dimethylamino chloroethanes, obtain doxylamine, last doxylamine and butanedioic acid salt-forming reaction obtain doxylamine succinate. This preparation technology reaction efficiency is high, and cost is lower, is applicable to industrialized production. |
