Abstract

Pyrimidine formation from active methyl group on heterocycles is described. 2-Methyl-pyridine (I), -quinoline (III), -pyrazine (IX), -benzothiazole (XX), 2,4-dimethyl-quinoline (VII), and -thiazole (XIII) were successful in pyrimidine formation. 2-Methyl-imidazole (XI), -benzimidazole (XV), -benzoxazole (XVI), and 2,4-dimethyloxazole (XII) were unsuccessful. Compound (III) gave pyrazine (V) and pyridine (VI) derivatives and pyridine formation occurred also in XX.
