An improved synthesis of the bicyclic spiro compound 2-oxa-6-azaspiro[3.3]heptane is presented. While this compound is often isolated as an oxalate salt, its isolation as a sulfonic acid salt yields a more stable and more soluble product. With these improved properties access to a wider range of reaction conditions with the spirobicyclic 2-oxa-6-azaspiro[3.3]heptane has been enabled.

Process development work to provide an efficient manufacturing route to a MCHr1 antagonist is presented herewith. Features of this development work include a scalable manufacturing route to the useful 6-oxa-2-azaspiro[3.3]heptane building block and the use of a (soluble) alternative to sodium triacetoxyborohydride.
