Versuchsvorschrift
In a manner analogous to Example 1, by condensing rac-2-hydrazino-3-(1-methylpropyl)-5-(3-pyridyl)pyrazine with diethyl (imidazol-4-ylmethyl)malonate there is obtained ethyl (RS)-8-[(RS)-1-methylpropyl]-α-(imidazol-4-ylmethyl)-6-(3-pyridyl)-s-triazolo[4,3-a]pyrazine-3-acetate, MS: 419 (M)+, which is converted into the above acid by alkaline saponification.
