Abstract: <smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="metricconverter"> 2-Methylsulphanyl-5-aminothiazole-4-carboxamide <b style="">1 </b>has been used as a convenient precursor for the synthesis<b style=""> </b>of new thiazolo[4,5-<i style="">e</i>][1,2,4-triazolo][4,3-<i style="">c</i>]pyrimidines <b style="">5 </b>and the corresponding tetrazolo analogue <b style="">7</b>. A mesoionic isomer <b style="">8</b> seems to exist along with <b style="">7</b>. Interesting heteroarylthiazolo pyrimidine<b style=""> </b>motifs have also been prepared <i style="">via</i> suitably substituted thiazolo[5,4-<i style="">d</i>]pyrimidines.</smarttagtype>
