Abstract Torasemide, a pyridine-3-sulfonylurea derivative, is a high-efficiency loop diuretic. During the process development of torasemide, five process-related substances, which have been specified in the pharmacopeia, would be produced. In this study, all these related substances, including compounds A–E, were synthesized via simple procedures and subsequently characterized by 1H nuclear magnetic resonance (NMR), 13C NMR, and mass spectrometry. Particularly, a simple synthetic method for compound A has not been found in previous literature. It is worth noting that other related substances could be prepared from compound B in one or two steps. The availability of these related substances could allow for quality control in the process of torasemide.
