Vedantham, Ravindra published the artcileImproved One-Pot Synthesis of Citalopram Diol and Its Conversion to Citalopram, Name: 1-(3-(Dimethylamino)propyl)-1-(4-fluorophenyl)-3-oxo-1,3-dihydroisobenzofuran-5-carbonitrile, the publication is Organic Process Research & Development (2013), 17(5), 798-805, database is CAplus.

An improved process is developed for the preparation of citalopram diol, I which involves two consecutive Grignard reactions in situ followed by an efficient and simple workup process with improved overall yield. Process development efforts for conversion of I·HBr into citalopram, II·HBr, and a control strategy for impurities are discussed. The present work addresses the challenges associated with the process development and scale-up of citalopram such as handling of unstable intermediates, control of various potential impurities, and process safety to achieve an economic and scalable process.
