Reaktionsschritte

4-(2-Cyano-phenyl)-3,6-dihydro-2H-pyridine-1-carboxylic acid tert-butyl ester (0.2 g) was dissolved in IMS (15 mL) and palladium on carbon (10%; 0.08 g) in water (0.5 mL) was added. Ammonium formate (0.3 g) was added and the mixture heated at reflux for 0.5 hour. The mixture was allowed to cool, filtered and the solvent removed by evaporation to give the title compound as a clear colourless oil (0.15 g). LCMS m/z 287.3[M+H]+. R.T.=4.63 min (Analytical Method 4).
