Abstract
Improvements in the procedure for obtaining pyrimidine composed of thiazolium and pyridinium, characterized by heating at temperatures of 100-135º in dimethylsulfoxide a 2-alkyl-4-amino-5-chloromethyl-pyrimidine with a thiazole or a pyridine, adding to the mixture an arylsulfonic acid such as p-toluenesulfonic acid and the resulting mass diluted in an alcohol of one to four carbon atoms, to obtain p-toluenesulfonates of (2-alkyl-4-amino-5-pyrimidylmethyl) -thiazolonium or pyridinium.
