The reaction of methylhydrazine with N-cyanoazomethines 1 containing a thioalkyl leaving group yields the 3-amino-1,2,4-triazole derivatives 2, whereas the N-cyanoazomethines 1 containing an alkoxy leaving group give the isomeric 5-amino-1,2,4-triazoles 3.The yields are excellent and the position selectivity is high.The structures of the 1,2,4-triazole derivatives were determined with the aid of proton-coupled 13C-NMR. spectra.
