実験手順
A solution of 20.0 g of 2-isopropylaminobenzaldehyde, 29.4 g of diethyl malonate, 10 ml of piperidine, 10 ml of acetic acid and 500 ml of toluene was heated to reflux for 13 hours. The reaction solution was washed with water and then with saturated sodium hydrogencarbonate aqueous solution, and dried over anhydrous magnesium sulfate. The solvent was distilled off to give 52 g of ethyl 1-isopropyl-2-oxo-1,2-dihydro-3-quinolinecarboxylate as the crude product.
