Development of a Scalable Synthesis of Gastrazole (JB95008): A Potent CCK2 Receptor Antagonist
摘要:
A practical and scalable synthesis was developed that was used to prepare multikilogram batches of gastrazole, a selective cholecystokinin-2 receptor antagonist. In addition, evidence was found to indicate an amide bond-forming reaction proceeded via the isoimide of a benzimidazoleamide acid derivative.
