    Abstract: A method for the manufacture of citalopram characterized in (i) reaction of 1-(4-fluorophenyl)-1-(3-dimethylaminopropyl)-5-halophthalane with an activated magnesium to form the Grignard reagent null3-null1-(4-fluorophenyl)-1,3 dihydro-isobenzofuran-1-ylnullpropylnulldimethylamine 5-magnesium halide followed by (ii) reaction of null3-null1-(4-fluorophenyl)-1,3 dihydro-isobenzofuran-1-ylnullpropyl)dimethylamine 5-magnesium halide with a compound containing a nullCN group bound to a leaving group to form citalopram.

    Abstract translation: 一种制备西酞普兰的方法,其特征在于(i)1-(4-氟苯基)-1-(3-二甲基氨基丙基)-5-卤代酞菁与活化镁反应形成格利雅试剂[3- [1-(4 - 氟苯基)-1,3-二氢 - 异苯并呋喃-1-基]丙基]二甲胺5-卤化镁,然后(ⅱ)[3- [1-(4-氟苯基)-1,3-二氢 - 异苯并呋喃-1-基] 吡啶-2-基]丙基)二甲胺5-卤化镁与包含与离去基团结合的-CN基团的化合物形成西酞普兰。
