Output (English): In the present invention there is disclosed a process for preparing citalopram, which preparation process is characterized by reacting the compound of the general formula IV, in which R represents a halogen atom or the group CFi3-(CFi2)-SOi2-O-, wherein n is an integer 0 through 8 inclusive, with a cyanide source in the presence of a palladium-based catalyst and a catalytic amount of  Cue+ or Zne2+ or with Zn(CN)i2 in the presence of a palladium-based catalyst, whereupon a corresponding 5-cyano compound i.e. citalopram of the general formula I in a free form or in the form of a pharmaceutically acceptable salt is isolated.
