A concise Pd catalyzed cross coupling reaction along with deprotection for the synthesis of a new series of pyrimidine derivatives

A new series of 2-amino, 4-azepanone, 5-aryl substituted derivatives of pyrimidine compounds were synthesized for the first time from the commercially available 2-amino-4-hydroxypyrimidine. The key step in the reaction is a conceptually new single step palladium catalyzed cross coupling along with the deprotection of N,N-diisopropylformimidamide using bis(triphenylphosphine)palladium(II) dichloride (PdCl2(PPh3)2).
