42 new compounds has been prepared. Reactions were performed in a total time of 40 min using microwave heating as a tool. A streamlined work-up process was also developed, allowing for facile isolation of the products. The methodology offers a more sustainable approach than previous routes, with only water and ethanol being used as solvents, and the products being isolated by means of a simple filtration

A continuous flow process for the synthesis of nitrobenzimidazole N-oxides from 2,6-dinitrochlorobenzene and amines or amino acids is reported. The process, performed in a two-step sequence, is faster than previously reported batch processes and avoids some of the isolation and purification steps.
