  Abstract: The synthesis of the four possible   2-amino- and 2-guanidino- 4-(2-amino- and   2-guanidinothiazolyl)pyrimi-dines is described and pKa. values   are calculated. Guanidinopyrimidines are more basic than   guanidinothiazoles. However, the reverse is true of the   corresponding amino heterocycles; the amino thiazole is more   basic than the amino pyrimidine.
