Abstract

GDC-9545 is a selective estrogen receptor degrader that is being developed as a treatment for ER+/HER2– breast cancer. A robust, convergent manufacturing process for GDC-9545 was developed. The process features a Wenker aziridine synthesis to produce the key starting material tryptamine 11, a highly efficient C–N coupling between aminoazetidine 9 and 2,6-difluoro-4-bromobenzaldehyde diethyl acetal (33) to construct key intermediate 10, and a crystallization-driven diastereoselective Pictet–Spengler reaction to furnish the active pharmaceutical ingredient GDC-9545·tartrate.

期刊介绍： The journal Organic Process Research & Development serves as a communication tool between industrial chemists and chemists working in universities and research institutes. As such, it reports original work from the broad field of industrial process chemistry but also presents academic results that are relevant, or potentially relevant, to industrial applications. Process chemistry is the science that enables the safe, environmentally benign and ultimately economical manufacturing of organic compounds that are required in larger amounts to help address the needs of society. Consequently, the Journal encompasses every aspect of organic chemistry, including all aspects of catalysis, synthetic methodology development and synthetic strategy exploration, but also includes aspects from analytical and solid-state chemistry and chemical engineering, such as work-up tools，process safety, or flow-chemistry. The goal of development and optimization of chemical reactions and processes is their transfer to a larger scale; original work describing such studies and the actual implementation on scale is highly relevant to the journal. However, studies on new developments from either industry, research institutes or academia that have not yet been demonstrated on scale, but where an industrial utility can be expected and where the study has addressed important prerequisites for a scale-up and has given confidence into the reliability and practicality of the chemistry, also serve the mission of OPR&D as a communication tool between the different contributors to the field.
