Reaction Steps
A mixture of 320 mg of 3-chloro-2-fluorobenzaldehyde, 252 mg of methyl 3-aminocrotonate and 510 mg of 2-(N-benzyl-N-methylamino)ethyl acetoacetate in 2 ml of 2-propanol was refluxed for 6 hours, and then the solvent was distilled off in vacuo. The residue was purified by the methods of a column chromatography on silica gel to yield 500 mg of the desired compound (106)
