Reaction Steps

A mixture of 5.7 g of 4-amino-5-methyl-1,2,4-triazol-3-one and 100 ml of alcohol is heated to the reflux temperature and 5.4 g of pyridine-3-carbaldehyde and 2 drops of 6N hydrochloric acid are added thereto. After 14 hours 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. 3.4 g of the title compound having a melting point of 208-210° are obtained.
