| abstract | Process for the selective preparation of (1h-1,2,4-triazol-1-yl) alkanols, hydrazinyl alkanol compound obtained by such process and its use. The present invention describes a process for the selective preparation of (1h-1,2,4-triazol-1-ii) alkanols useful as synthesis intermediates and as pharmaceutical, veterinary and agrochemical active ingredients, as well as the use of their intermediates, the processing conditions. In accordance with the present invention, oxiranes and halohydrins are reacted with hydrazine (in any presentation form, hydrates or salts) to yield hydrazinylalkanol type intermediates, which are converted to (1 h -1,4-triazol-1-iii ) alkanols by reaction with some 1,2,4-triazolyl forming reagent. The discovery technique is an advance over the state of the art by not allowing the formation of 4-position substituted isomers of the triazole ring, the (1h-1,2,4-triazol-4-yl) alkanols. The methods described in the present invention are particularly advantageous in relation to the state of the art because of their higher yields, shorter processing times, simplified unit operations, easier recovery of unreacted and auxiliary materials, full selectivity for regioisomer formation. |
