How is N-{15-[(2,5-Dioxo-1-pyrrolidinyl)oxy]-15-oxo-3,6,9,12-tetraoxapentadec-1-yl}-4-formylbenzamide (CAS: 1353011-74-1) typically synthesized?

N-{15-[(2,5-Dioxo-1-pyrrolidinyl)oxy]-15-oxo-3,6,9,12-tetraoxapentadec-1-yl}-4-formylbenzamide is usually synthesized through multistep reactions involving the formation of a 15-oxo-pentadecanoic acid derivative, followed by its esterification with a pyrrolidine derivative, and finally, the formation of the amide bond. The synthesis typically requires careful control of reaction conditions and the use of suitable catalysts to achieve high selectivity and yield.
