2-Methyl-2-Phenyl Propyl Acetate, an intermediate in the multi-step synthesis of Fexofenadine HCl, a widely used non-sedating antihistamine, is a compound of unique properties. Often referred to in synthesis protocols as a “Fexo Chloro” derivative, it forms the side chain structure leading to the final API. Its structural backbone facilitates alkylation and acylation steps during late-stage intermediate development. It plays a structural role in building the side-chain scaffold of the antihistamine API. It is a Stage 5 intermediate in the “Fexo Chloro” synthesis pathway.
