ABSTRACT
Condensation of dimethyl 2-chloro-6-methylpyridine-3,4-dicarboxylate with thiourea and its N-substituted derivatives is described. It has been found that depending on the kind of substituents in the starting thiourea derivatives, pyrido [3,2-e]-1,3-thiazine or pyrido [2,3-d] pyrimidine derivatives were formed.
