| titleOfInvention | 2-alkoxy-4-hydrazinopyrimidine compounds |
| abstract | 5-Alkoxy-1,2,4-triazolo[4,3-c]pyrimidine-3(2H)-thione compounds, such as 5-ethoxy-8-fluoro-1,2,4-triazolo[4,3-c]pyrimidine-3(2H)-thione, were prepared by cyclization of 2-alkoxy-4-hydrazinopyrimidine compounds, such as 2-ethoxy-5-fluoro-4-hydrazinopyrimidine, with carbon disulfide and hydrogen peroxide. The reaction can be carried out in the presence of a trialkylamine, such as triethylamine, in which case a trialkylammonium salt is obtained. The products are useful intermediates in the preparation of 5-alkoxy[1,2,4]triazolo[1,5-c]pyrimidine-2-sulfonamide herbicides. |
