Reaction Steps

A mixture of 14.5 g (85 mmole) of 5-chloro-7-methyltriazolo[1,5-c]pyrimidine and 15 g (200 mmole) of thiourea in 100 ml of methanol was heated at reflux for one hour, and then cooled to 0° C. The product was collected by filtration and recrystallized from a 50:50 mixture of ethanol and hexanes with treatment with decolorizing charcoal to provide 7-methyltriazolo[1,5-c]pyrimidine-5-thiol. The structural assignment was confirmed by nuclear magnetic resonance spectral analysis.
