Reaction Steps

A mixture of 3-(3-nitrophenyl)-1-phenyl-2-propen-1-one (20 g) and N-(2-morpholinoethyl)-3-aminocrotonamide (21.9 g) in toluene (200 ml) was refluxed for 5 hours. After allowing to cool at ambient temperature, the reaction mixture was concentrated in vacuo. The residue was subjected to a column chromatography on silica gel eluting with a mixture of ethyl acetate and tetrahydrofuran (100:1 V/V). The fractions containing the object compound were combined and concentrated in vacuo. The residue was recrystallized from ethyl alcohol to give 3-(2-morpholinoethylcarbamoyl)-2-methyl-4-(3-nitrophenyl)-6-phenylpyridine (11.0 g, yield 31.2 %).
