Versuchsvorschrift
A mixture of 4-{3-cyanophenyl)-2-methyl-3-(2- morpholinoethylcarbamoyl)-6-phenylpyridine (1.5 g) and Raney's Nickel (1.5 g) in 75% formic acid (40 ml) was refluxed for one hour under stirring. The reaction mixture was filtered and the filtrate was evaporated in vacuo. The residue was dissolved in a mixture of ethyl acetate and water and the resultant solution was adjusted to pH 8.0 with 20% aqueous potassium carbonate. The separated organic layer was washed with brine and dried over magnesium sulfate. The solvent was evaporated in vacuo and the residue was subjected to a column chromatography on silica gel and eluted with a mixture of ethyl acetate and diisopropyl ether (8:2 V/V). The eluted solution was evaporated in vacuo and the residue was recrystallized from a mixture of ethyl acetate and diisopropyl ether to give 4-(3-formylphenyl)-2-methyl-3-(2-morpholinoethylcarbamoyl)-6-phenylpyridine (0.8 g).
