The reaction of 5-aminopyrimidine with benzenediazonium chloride, p-methylbenzenediazonium chloride and p-bromobenzenediazonium chloride, is described.The reaction leads to a mixture of compounds, i.e. 1-aryl-3-(pyrimidin-5-yl)triazene (6), 5-amino-4-aryl-6-arylazopyrimidine (7) and 4-aryl-6-arylazo-5-hydroxypyrimidine (8).The yields are found to be strongly dependent on the substituents present in the diazonium salt.Attempts to rearrange 1-(p-bromophenyl)-3-(pyrimidin-5-yl)triazene (6c) under basic and acidic conditions into a 1,2,3-triazole derivative failed.
