Used as a key synthetic intermediate in the preparation of rivaroxaban, a potent oral anticoagulant. It plays a critical role in the stepwise assembly of the drug’s molecular framework, particularly in forming the ester and amide linkages essential for biological activity. Due to its phthalimido and ester functionalities, it enables selective reactions in multi-step synthesis, improving yield and purity during manufacturing. This analog is especially valuable in process chemistry for scaling up production of rivaroxaban under controlled conditions.
