IMPROVED PROCESSES FOR THE PREPARATION OF DABIGATRAN ETEXILATE USING NOVEL INTERMEDIATES

摘要

Disclosed herein are novel, commercially viable and industrially advantageous processes for the preparation of Dabigatran or a salt thereof, in high yield and purity, using novel intermediate compounds. The novel process solves the drawbacks associated with the prior processes and is commercially viable for preparing Dabigatran and its salts or derivatives thereof.
