Rogletimide, also known as pyridoglutethimide, is a medication which was never marketed.[1] It is related in chemical structure to the sedative/hypnotic drug glutethimide, but instead has pharmacological activity as a selective aromatase inhibitor similar to the related drug aminoglutethimide and has no significant sedative-hypnotic effect.[2] This makes it potentially useful in the treatment of breast cancer, and with fewer side effects than aminoglutethimide, but its lower potency caused it to be unsuccessful in clinical trials.[1][3]


Synthesis

Synthesis:[4] Patent:[5]

Base catalyzed alkylation of ethyl 4-pyridylacetate [54401-85-3] (1) with iodoethane gives ethyl 2-(4-pyridyl)butyrate [76766-56-8] (2). Base catalyzed conjugate addition of the carbanion to acrylamide (3) gives (4). The last step is an intramolecular cyclization to rogletimide (5).
