palladium-catalyzed cross-couplingreaction of triorganoindium reagents (R3In) with 5-bromo-2-chloropyrimidine proceeds chemoselectively, in good yields, to give 5-substituted-2-chloropyrimidines or 2,5-disubstituted pyrimidines using 40 or 100 mol % of R3In, respectively. Sequential cross-couplings are also performed, in one pot, using two different R3In. This method was used to achieve the first synthesis of the
