Methyl 3-aminocrotonate → 2-(N-benzyl-N-methylamino)ethyl methyl 2,6-dimethyl-4-(2-fluoro-3-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylate

Participants

Reaction Steps

A mixture of 330 mg of 2-fluoro-3-nitrobenzaldehyde, 252 mg of methyl 3-aminocrotonate and 506 mg of 2-(N-benzyl-N-methylamino)ethyl acetoacetate in 2 ml of 2-propanol was refluxed for 12 hours, and then the solvent was distilled off in vacuo. The residue was purified by the method of a column chromatography on silica gel to provide 492 mg of the desired compound (104).
