Palladium catalyzed Suzuki–Miyaura cross-coupling reactions are reported for the synthesis of monoarylated (at the C8 position) and symmetrical diarylated (at the C6 and C8 positions) imidazo[1,2-a]pyrazines. Monoarylated products have also been used to synthesize unsymmetrical C6/C8 diarylated products. These compounds were screened for in vitro antitumor activities against a preliminary tumor cell line panel assay.
