Procedure

A mixture of 40 g (0.014 mole) of 2-benzylthio-4-chloro-6-n-propylpyrimidine (from Part B) and 15 g (0.3 mole) of hydrazine hydrate in 300 ml of ethanol was heated at reflux for 2 hours, cooled and evaporated. Water was added to the residue. The white solid was collected by filtration and dried to provide 2-benzylthio-4-hydrazino-6-n-propylpyrimidine. The structural assignment was confirmed by infrared and nuclear magnetic resonance spectral analyses.
