Abstract: Let $ U$ be the group of units of the integral group ring of a finite group $ G$. We give a set of generators of a subgroup $ B$ of $ U$. This subgroup is of finite index in $ U$ if $ G$ is an odd nilpotent group. We also give an example of a $ 2$-group such that $ B$ is of infinite index in $ U$.
