실험 절차

A mixture of 4 g of 4-amino-1,2,4-triazol-3-one and 100 ml of alcohol is heated to the reflux temperature and 4.3 g of pyridine-3-carbaldehyde and 2 drops of 6N hydrochloric acid are added thereto. After 30 minutes under reflux the reaction mixture is cooled to 20°. The product that has precipitated is then filtered off with suction and dried under a high vacuum. 4.6 g of the title compound having a melting point of 264°-265° are obtained.
