Participants

Reaction Steps

In a manner analogous to that described in Example 1(D), from 3,5-dioxo-1,2,4-triazolidine-4-propionic acid, prepared as described in Example 2(C) and hexa-2,4-dienoic acid, there was obtained in 76% yield 5-carboxy-2,3,5,8-tetrahydro-8-methyl-1,3-dioxo-1H-1,2,4-triazolo[1,2-a]pyridazine-2-propionic acid of melting point 184°-186° C. (from acetonitrile).
