1,6-Dihydro-7-(and 8-)methyl-8-azapurine-2-thione (1a and b) were made by the action of carbon disulphide on 4-amino-5-aminomethyl-1-(and 2)-methyl-1(and 2)H-1,2,3-triazole (2c and d) respectively. These thiones were methylated to the corresponding 2-methylthio-derivatives (5a and b), which were oxidized by manganese dioxide to 7-(and 8-)methyl-2-methylthio-8-azapurine (6a and b), and the latter was
