Reaction Steps

1-Hydroxy-1H-1,2,3-triazole-4-carboxylic acid was prepared by combining 1-hydroxy-1H-[1,2,3]triazole-4-carboxylic acid ethyl ester (2.0 g, 13 mmol), EtOH (25 mL, 430 mmol), and a pre-dissolved solution of LiOH monohydrate (1.6 g, 38.2 mmol) and water (10 mL, 600 mmol). The mixture was stirred at room temperature for 4 hours, then partially concentrated and acidified with HCl to cause precipitation. The solid was filtered and dried under vacuum to give 1.3 g of the desired acid.
