Compound 1, a norepinephrine/serotonin reuptake inhibitor (NSRI) for the treatment of fibromyalgia, has been synthesized in optically pure form in six linear steps and 48% overall yield with no chromatography. This route features a novel and efficient intramolecular cyclization to generate the indazolone core via a diazotization reaction and the preparation of a stable polymorph of the tartaric acid salt as the desired final form. The original ...
