Reaction Steps

To a solution of 4-imidazoleacetic acid methyl ester hydrochloride (3.95 g, 22.4 mmol) in ethanol (150 ml) is added N,N-diisopropylethylamine (2.90 g, 16.6 mmol) and hydrazine (1.79 g, 36 mmol). The solution is refluxed at 70° C. overnight. The solution is concentrated and recrystallized from methanol to give 4-imidazoleacetic acid hydrazide as a white solid. The yield is 2.46 g, 78%.
