Herein, the amide coupling of six primary amines with the sodium salt of diazabicyclooctane acid in an aqueous medium without an additional base/surfactant or organic solvent is described. The product was efficiently isolated from the reaction through simple filtration and recrystallized using hot water treatment as a swift and cost-effective process. The methodology was implemented on a kilogram scale
