Nucleophilic aromatic substitution?

If you have NO2 group meta to Br in a benzene ring, and you undergo KNH2 in liquid NH3, will the NH2 add to the meta position of NO2? If this is wrong and NH2 add to ortho position of NO2, is it because intermolecular interaction between O of NO2 and H of NH2 stronger? Please clarify this confusion... thanks...:)
