| titleOfInvention | METHOD FOR THE PREPARATION OF ESCITALOPRAM |
| abstract | 1. A method for the preparation of escitalopram having the following Formula: comprising: a) .- the optical resolution of the racemic compound having the following Formula: In which X is as defined above and Z is OH or a group projection, by fractional crystallization of a diastereomeric salt thereof, or by formation and separation of the diasteromic esters thereof optionally followed by hydrolysis of the correct diasteromeric ester, so as to form a compound of the following Formula: in which X is as defined above and Z is OH or a leaving group, and when Z is OH, by converting Z into a leaving group, followed by ring closure of the compound of Formula (III) so as to form a compound of the Formula: (ll) in which X is halogen or any other group that can be converted into a cyano group, ... |
