Procedure
In a manner analogous to that described in Example 1, by condensing 2-benzyl-3-hydrazino-6-(3-pyridyl)pyrazine with diethyl (imidazol-4-ylmethyl)malonate there is obtained ethyl rac-8-benzyl-α-(imidazol-4-ylmethyl)-6-(3-pyridyl)-s-triazolo[4,3-a]pyrazine-3-acetate, MS: 453 (M)+, which is converted into the above acid by alkaline saponification.
