Abstract:
The invention relates to new and improved processes for the preparation of Indacaterol and pharmaceutically acceptable salts thereof as well as intermediates for the preparation of Indacaterol. The new process avoids the use of the epoxide compound known in the art and the impurities associated therewith and results in a higher yield.
