Reaction of 1-benzyl-3,5-dibromo-1H-[1,2,4]triazole (3) with cesium fluoride yielded selectively 1-benzyl-3-bromo-5-fluoro-1H-[1,2,4]triazole (4). Debenzylation and realkylation afforded 1-alkyl-5-bromo-3-fluoro-1H-[1,2,4]triazoles 7, which reacted with a wide variety of nucleophiles to give 5-substituted 1-alkyl-3-fluoro-1H-[1,2,4]triazoles.
The present invention discloses compounds of Formula (I) wherein the variables in Formula (I) are defined as described herein. Also disclosed are pharmaceutical compositions containing such compounds and methods for using the compounds of Formula (I) in the prevention or treatment of HCV infection.
