Hi
you can get biphenyl with two bromine atoms at 4,4' positions from aldrich, supleco, Alfa Aesar.
However you can synthesize these by using copper acetate. one of the reference is

Journal of Organic Chemistry, 68(26), 10130-10134; 2003

or by the brominationo of biphenyl

Organic Syntheses, 31, 29-30; 1951

Regarding the other compound with amino group they are aviable in small quantity from

Labo test building block

Ambinter Screening Library

Frinton Labs

You can synthesise them by either the reduction of the corresponding nitro compound

Journal of Organic Chemistry, 23, 1504-6; 1958

or from 2-nitrochlorbenzene

ref:

Bulletin of the Chemical Society of Japan, 48(6), 1868-74; 1975
