Route Design to Manufacture: Synthesis of the Heterocyclic Fragment of AZD5718 Using a Non-cryogenic Lithiation-Alkoxycarbonylation Reaction

Route design and process development of the small nitrogen heterocycle 2·HCl, a constituent of AZD5718 (1), is described. The novel synthetic sequence to 2.HCl involves a desymmetrizing alkylation ...
