Synthesis of 4,6-disubstituted 2-(4-morpholinyl)pyrimidines by cross-coupling reactions using triorganoindium compounds.

4,6-Disubstituted-2-(4-morpholinyl)pyrimidines, an important class of bioactive compounds, have been synthesized from 4,6-dichloro-2-(4-morpholinyl)pyrimidine by selective and sequential palladium catalyzed cross-coupling reactions using triorganoindium reagents. This methodology, being efficient and versatile, allowed the synthesis of a variety of non-symmetrical pyrimidines functionalized at C-4 and C-6 positions.
