An improved synthesis of the dual-function radiosensitizer alpha-[[2-bromoethyl)amino]methyl]-2-nitro-H-1-imidazole-1-ethanol (2, RB 6145) has been developed. Previously, the synthetic difficulties associated with this compound limited its attractiveness as a clinical candidate, although its radiosensitizing activity in preclinical models warranted its further development. The synthesis described uses a 2-oxazolidinone as an aziridine equivalent and provides 2 in 47% yield.

The present invention is novel nitroimidazoles useful as radiosensitizing or chemosensitizing agents in the treatment of hypoxic tumor cells. Also, the present invention is a novel process for preparing both known and novel nitroimidazoles having novel intermediates. The process advantageously reduces the number of process steps, provides increased yield with both greater safety and greater control of stereo-isomerism in the products.
