The present invention discloses a simple in situ method for the purification of citalopram acid addition salts without isolating crystalline citalopram base as a solid, wherein citalopram base is treated with metal hydrides in solvent medium followed by acid addition, to remove structurally similar impurities by filtration to get crude citalopram acid addition salts. The resulting citalopram salts are subjected to simple purification to get pharmaceutically acceptable acid addition salts. The said citalopram base is prepared by subjecting 5-cyanophthalane to an eco-friendly and safe C-alkylation reaction with 3,N,N dimethylaminopropyl chloride in the presence of strong base in a mixture of dimethylsulfoxide and toluene.

Recently, we published a synthesis of escitalopram (S-1) consisting of the resolution of didesmethylcitalopram (3) and subsequent methylation of S-didesmethylcitalopram (S-3) (Org. Process Res. De v. 2007, 11, 289-292). Some of our observations regarding citalopram resolution and C-alkylation of a benzofuran analogue (2) to produce didesmethylcitalopram (3) were disputed by Dr. Dancer of H. Lundbeck (preceding article). A detailed response to his comments regarding stabilization of the 3-chloroproylamine free base by dilution with certain solvents, its storage and handling, optimized experimental conditions for C-alkylation to prepare didesmethylcitalopram, and a corrected process for citalopram resolution are included.

Our strategy relies on electrophilic activation coupled to in situ selective selenium-mediated dehydrogenation. The alpha,beta-unsaturated products were obtained in moderate to excellent yields, and their synthetic versatility was demonstrated by a range of transformations. Mechanistic experiments suggest formation of an electrophilic SeIV species.
