| titleOfInvention | PROCEDURE FOR THE PREPARATION OF A CIANOISOBENZOFURAN. |
| abstract | A process for the preparation of citalopran and the pharmaceutically acceptable salts thereof is described, by reacting 5-cyanophthalide with a 4-fluorophenylmagnesium halide, reducing 3-hydroxymethyl-4 (4-fluorobenzoyl) benzonitrile with a ketone reducing agent. To alcohols, send 3-hydroxymethyl-4 - [(4-fluorophenyl) hydroxymethyl) benzonitrile obtained in this way to a cyclization reaction to provide 1- (4-fluorophenyl) -1,3-dihydro-5-isobenzofurannocarbonitrile without 1 , 1-bis (4-fluorophenyl) -1,3-dihydro-5-isobenzofurancarbonitrile and treat 1,1-bis (4-fluorophenyl) -1,3-dihydro-5-isobenzofurannocarbonitrile with a 3- (dimethylamino) halide ) propyl in the presence of a base. |
