So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Lee, H. H.; Palmer, B. D.; Wilson, W.

We’ll tell you more about this compound (cas:121816-79-3).
A four-step synthesis of 5-[N,N-bis(2-chloroethyl)amino]-1-methyl-2-nitroimidazole from 1-methyl-2-nitroimidazole is described. This compound showed similar hypoxia-selective cytotoxicity to the dinitrobenzamide mustard SN 23862 in UV4 cells (ca. 40-fold), and superior selectivity (>7-fold) in repair-competent AA8 cells.
