Abstract
The invention comprises 1-methylthioguanine and its preparation by reacting 1-methylguanine with phosphorus pentasulphide in an inert solvent, e.g. pyridine and similar bases. The reaction is preferably effected by heating the reaction mixture to at least 100 DEG C., and advantageously the mixture is refluxed for 3 hours. An example is given.
