実験手順

A mixture of 460 mg of 2-chloro-3-fluorobenzaldehyde, 360 mg of methyl 3-aminocrotonate and 820 mg of 2-(N-benzyl-N-methylamino)ethyl 3-aminocrotonate in 4 ml of 2-propanol was refluxed for 8 hours, and then the solvent was distilled off under reduced pressure. The residue was purified by a column chromatography on silica gel to provide 860 mg of the desired compound (110).
