Abstract
In the title compound, C20H21BrN4O2, the pyrrolopyrimidine ring system is essentially planar. The bromophenyl ring forms a dihedral angle of 33.1 (1)° with the pyrrolopyrimidine ring system. C—H⋯N hydrogen bonds link the molecules into cyclic centrosymmetric R22(18) dimers, which are crosslinked along the [\overline{1}10] direction through C—H⋯O hydrogen bonds.
