Commercial Synthesis of (S,S)-Reboxetine Succinate: A Journey To Find the Cheapest Commercial Chemistry for Manufacture

The development of a synthetic process for (S,S)-reboxetine succinate, a candidate for the treatment of fibromylagia, is disclosed from initial scale-up to deliver material for registrational stability testing through to commercial route evaluation and subsequent nomination. This entailed evaluation of several alternative routes to result in what would have been a commercially attractive process for launch of the compound.
