Reaction Steps

A suspension of 3-amino-s-triazole (28 g) and diethyl acetonedicarboxylate (100 g) in 100 ml of acetic acid was refluxed for six hours. After cooling to room temperature, 150 ml of concentrated hydrochloric acid was added under ice cooling, the crystals thus formed were collected by filtration, and washed twice with 100 ml of ethanol, then once with 100 ml of ether, affording 71 g of the objective compound as colorless crystals.
