Abstract
Reactions of α-arylthio-α-oxoketene dithioacetals 1 with guanidine nitrate in the presence of sodium methoxide in refluxing methanol afford novel 2-amino-4-aryl-5-arylthio-6-methoxy-pyrimidines. Similarly, when compounds 1 are reacted with hydrazine hydrate in refluxing ethanol, novel substituted 3(5)-aryl-4-arylthio-5(3) methylthiopyrazoles are obtained in high yields.
