1,2,4-Triazoles. VII. Methylation of 1,2,4-triazoles.

Chemical and Pharmaceutical Bulletin, 1976
The methylations of twenty-five 1, 2, 4-triazoles with methyl iodide and diazomethane were studied and substituent effects on the product ratios are discussed. Methylation of 1, 2, 4-triazole and its symmetrically 3, 5-disubstituted derivatives occurred almost exclusively at the 1-position.
