実験手順

A mixture of 1-(4-aminophenyl)-2-methyl-1-propanone (0.0637 mol) and methyl 2-chloro-3-pyridinecarboxylate (0.0637 mol) in 2-methoxyethanol (200 ml) was stirred and refluxed for 90 hours. The mixture was taken up in water and EtOAc and extracted with EtOAc. The organic layer was separated, dried, filtered and the solvent was evaporated, yielding 22.6 g of methyl 2-[[4-(2-methyl-1-oxopropyl)phenyl]amino]-3-pyridinecarboxylate (interm. 20).
