Syntheses from Acyclic Compounds and Other Heterocycles [Pg.19]

Ethoxymethylenecyanoacetate and the hydrazone 103 give a triazolopyridi-none other hydrazones, such as 104 give 7-aminotriazolopyridines (91JHC797). [Pg.19]

A triazolium ylide reacts with acetylene dicarboxylate to produce compound 105 via a pyrrolotriazole (83JCS(P1)1317), and 2-methoxypyridine can react with the tetrazole 106 to give either a triazolopyridine or a pyridopyrazine (93AP (326)427). [Pg.20]
