실험 절차
Reaction of N-cyanobismethylthiomethyl-eneimine with ethyl thioglycollate gives ethyl 2-methylthio-4-aminothiazole-5-carboxamide. Cyclization with formamide or equivalent, followed by desulfurization of the methylthio gives a thiazolopyrimidone, which can be activated by Viismeier reagent ,and the chloride displaced by the desired amine to give the desired thiazolo[4,5-d]pyrimidine derivatives as shown above.
