6-Alkyl- and 5,6-Dialkyl-2-methoxy-4(3H)-pyrimidinones in the Transformations of Pyrimidines. Conversion into 2-Substituted Amino- and 4-Chloro-Pyrimidine-Derivatives

Abstract
6-Alkyl- and 5,6-dialkyl-2-methoxy-4(3H)-pyrimidinones are transformed into the 2-alkyl(and 2-aryl)amino-derivatives, in good yield, by reaction with the corresponding amines. Treatment with SOCl2 -DMF gives 6-alkyl- and 5,6-dialkyl-2-methoxy-4-chloro pyrimidines.
