Participants

Reaction Steps

4.57 g (31 mmol) of 4-chloropyridine and 5.03 g (31 mmol) of ethyl 4-aminobenzoate were dissolved in 100 ml of xylene. 12.7 ml (92 mmol) of triethylamine was added to the obtained solution and the resultant mixture was heated under reflux for 50 hours. The solvent was evaporated, and the residue was diluted with water. After the extraction with dichloromethane followed by washing with saturated Aqueous NaCl solution and drying over anhydrous magnesium sulfate, the solvent was evaporated and the residue was purified by the silica gel column chromatography to obtain the title compound.
