2-Amino-4-hydroxy-6-mercaptopyrimidine (II) has been synthesized by condensation of guanidine with methyl ethoxycarbonyl-dithioacetate (I). The structure of the condensation product II has been proved (a) by desulfurization to isocytosine (III), (b) by comparison with a specimen prepared by treatment of 2-amino-4-chloro-6-hydroxypyrimidine (IV) with NaSH.
