    摘要: The present invention is directed to novel processes for the preparation of citalopram comprising halogenation of a phthalide compound of formula II, wherein R is a suitable group to be changed to CN, to afford an acid halogenide compound of formula III wherein R is as defined above and X is halogen, and thereafter obtaining citalopram through two successive reactions with suitable organometallic halides or organoboranes or by a reaction with organometallic 4-fluorophenylhalide or 4-fluorophenylborane followed by reduction and alkylation, and an exchange of R to cyano to afford citalopram. The order of the reactions can be varied depending e.g. on the starting compound used.
