Reaktionsschritte
Scheme M depicts a specific synthesis of a pyrazinyl propionic acid. Methylpyrazine anion is condensed with trichloroacetaldehyde followed by treatment with base (hydroxide), then acidification to produce 3-(-Pyrazinyl) Acrylic Acid 75. This acid is then catalytically hydrogenated over palladium on charcoal to yield 3-(2-Pyrazinyl)propionic Acid 76.
