Reboxetine mesilate, PNU-155950E, FCE-20124, Vestra, Norebox, Edronax

甲磺酸瑞波西汀 瑞波西汀 瑞波西汀Chemical Name: (?-(R*,R*)-[2-[alpha-(2-Ethoxyphenoxy)benzyl]morpholine methanesulfonate
CAS No. 98769-84-7, 98769-81-4 (free base), 71620-89-8 (undefined stereoch., free base)
项目整合开发状态: Launched-1997
项目研究机构: Pfizer (Originator)
合成路线:Epoxidation of trans-cinnamyl alcohol (A) gives compound (I),which in turn is reacted with sodium 2-ethoxyphenate (B) to give the diol (II).The primary alcoholic group of (II) is reacted with p-nitrobenzoyl chloride to obtain (III),and (IV) is prepared by treatment of (III) with methanesulfonyl chloride.By treatment of (IV) with sodium hydroxide in an aqueous/dioxane solution the epoxide (V) is obtained in high yield,and this reaction causes inversion of configuration at C-2 carbon atom.Treatment of (V) with aqueous methanolic ammonia gives (VI),which in turn is acylated to (VII) with chloroacetyl chloride and cyclized to morpholone (VIII) with potassium tert-butoxide.The reduction to the final compound FCE-20124 is performed with [sodium bis(2-methoxyethoxy)aluminum hydride] (RED-AL) in toluene.
