Reaction Steps

64 mg of dimethyl 5-(5-cyano-1-pentinyl)-pyridine-2,4-dicarboxylate (from Example 11) are dissolved in 25 ml of methanol and, after addition of the palladium catalyst (10% strength on charcoal), are hydrogenated. The reaction has ended after 4 hours (thin layer control). The catalyst is filtered off and the solution is concentrated in vacuo. The colorless oil is chromatographed on silica gel.
