Versuchsvorschrift

A mixture of methyl 3-amino-3-(3-nitrophenyl)acrylate (45 g) and 1-phenyl-2-buten-1-one (44 g) in n-butanol (450 ml) was refluxed for 4 hours. After allowing to cool at ambient temperature, the reaction mixture was evaporated in vacuo. The residue was subjected to a column chromatography on silica gel (500 g) eluting with benzene. The fractions containing the object compound were combined and concentrated under reduced pressure to give methyl 4-methyl-2-(3-nitrophenyl)-6-phenyl-3-pyridinecarboxylate (4.10 g).
