One of theconcerns regarding the sustainability of the previously developed amidation protocol, mainly arising from the use of dimethyl sulfoxide (DMSO), wassuccessfully addressed through reoptimization. Ethylacetate cannow serve as an effective, environmentally friendly alternative reactionmedium. Authors also present the results of a sensitivity study of the newlyoptimized amidation conditions, examining parameters such as O2 levels, concentrations, water content, and temperatures.
