Procedure

In a manner analogous to that described in Example 1, by condensing 2-hydrazino-3-propyl-5-(3-pyridyl)pyrazine with diethyl (imidazol-4-yl-methyl)malonate (J.Chem.Soc. 99, (1911) 1390) there is obtained ethyl rac-α-(imidazol-4-ylmethyl)-8-propyl-6-(3-pyridyl)-s-triazolo[4,3-a]pyrazine-3-acetate, MS: 405 (M)+, which is converted into the above acid by saponification analogously to Example 1.
