Reaction Steps

A solution of 2-methyl-5-trifluoromethyl-2H-1,2,3-triazole-4-carboxylic acid methyl ester [Compound Number 1.15] (2.09 g; 0.01 mol) and KOH (86%; 0.783 g; 1.2 eq.) in THF (50 ml) was heated at reflux temperature for 3.5 hours. The solution was evaporated, the residue was dissolved in water and acidified to pH 1-2 with HCl (1M). Evaporation of the aqueous solution followed by continuous extration in ethylacetate for 20 hours gave of Compound No 1.13 (2.11 g; 100%) as a crystalline solid.
