Abstract
Metallation of 1-[2(trimethylsilyl)ethoxy]methyl-1H-pyrazole or 1-[2-(trimethylsilyl)ethoxy]methyl-1H-1,2,4-triazole, respectively, with one equivalent of n-BuLi followed by reaction with appropriate electrophiles leads to 5-substituted 1-[2-(trimethylsilyl)ethoxy] methyl-1H-pyrazoles and 5-substituted 1-[2-(trimethylsilyl)ethoxy] methyl-1H-1,2,4-triazoles. Deprotection can be achieved either by heating with aqueous ethanolic HCl or by treatment with anhydrous tetrabutylammonium fluoride
