Meldonium hydrate, Quaterin, Mildronate, MET-88, Q-4224-IOS, THP(anhydrous)

米屈肼(二水合物) 米屈肼 Chemical Name: 3-(2,2,2-Trimethylhydrazinium)propionate dihydrate; 2-(2-Carboxyethyl)-1,1,1-trimethylhydrazinium hydroxyde inner salt dihydrate
CAS No. 86426-17-7, 76144-81-5 (anhydrous)
项目整合开发状态: Phase II
项目研究机构: Latvian Institute of Organic Synthesis (Originator), Taiho (Licensee)
合成路线:Methyl 3-(2,2-dimethylhydrazino)propionate (I) is treated with a methyl halide (II,X = halo) or dimethyl sulfate (II,X = CH3SO4) to give the appropriate trimethylhydrazinium salt (III),which is transferred to 3-(2,2,2-trimethylhydrazinium)propionate (IV) by Amberlite IRA-400 (OH form).After crystallization from ethanol the inner salt is obtained as a dihydrate.
