Reaction Steps

1-Hydroxy-1H-[1,2,3]triazole-4-carboxylic acid ethyl ester (2.0 g, 13 mmol) and EtOH (25 mL) were combined with a pre-dissolved solution of lithium hydroxide monohydrate (1.6 g, 38.2 mmol) and water (10 mL), and stirred at room temperature for 4 hours. The mixture was partially concentrated and acidified with HCl to cause precipitation. The solid was filtered and dried under vacuum to yield the title compound (1.3 g).
