Reactions of Cyclic Oxalyl Compounds, Part 30: Some Reactions with N-Amino-pyrimidine Derivatives

1-Amino-5-benzoyl-4-phenyl-1H-pyrimidine derivatives 1 add arylisocyanates 2 to give the N,N'-disubstituted ureas 3 which can be cyclized by use of oxalyl dichloride to the imidazolyl-pyrimidinones(thiones) 4.In addition, 1 is transferred into the desaminated pyrimidines 6 either by diazotation reaction or by thermolysis of the parental functionalized pyrimidine derivatives 7.
