DESCRIPTION 1(S)-(-)-N-(a-ethylbenzyl)-3-hydroxy-2-phenyl-4-quinoline carboxamide 2.49 g (9.4 mmols) of <strong>[485-89-2]3-hydroxy-2-phenyl-4-quinoline carboxylic acid</strong> (CAS [485-89-2]) were suspended in 150 ml of a mixture of THF/MeCN 7:3, respectively; 1.40 g (10.3 mmols) of 1-hydroxybenzotriazole (HOBT) were added to the suspension and then 1.27 g (9.4 mmols) of (S)-(-)-1-phenylpropylamine, dissolved in 20 ml of methylene chloride were added dropwise over 10 minutes period. The reaction mixture was stirred at room temperature for 30 minutes and then 2.13 g (10.3 mmols) of dicyclohexylcarbodiimide (DCC), dissolved in 20 ml of methylene chloride, were added dropwise and the reaction stirred overnight. 20 ml of H2O were added and the reaction stirred 30 minutes, then the solvent was evaporated in vacuo to dryness. The residue was taken up in EtOAc, the precipitated dicyclohexylurea (DCU) was filtered off and the filtrate washed with water, 20% citric acid, 5% NaHCO3, brine and the organic layer dried over Na2SO4 and the solvent evaporated in vacuo. The residue was purified by silica-gel (60-240 mesh) flash column chromatography, eluting with a mixture of hexane/EtOAc 9:1, containing increasing amounts of EtOAc, until the ratio 7:3. The purified product was crystallized from i-PrOH to yield 1.75 g of the title compound as a white solid. C25H22N2O2 M.P.=168-168.4 C.

YieldReaction ConditionsOperation in experiment
In DMF (N,N-dimethyl-formamide); at 10 - 20℃; for 2h;Product distribution / selectivity; [0059] A reaction flask was charged with dimethylformamide (DMF) (500 mL), 2,4-dichloro-5-methoxyaniline (100 g, 0.52 mol) and cyanoacetic acid (46.6 g, 0.55 mol). The mixture was cooled to 10 C. in an ice bath. To the cooled mixture was added, dropwise, a solution of N,N' dicyclohexylcarbodiimide (119.1 g, 0.58 mol) in DMF (240 mL) so as to keep the temperature below 15 C. After the addition was completed, cooling was discontinued and the reaction was stirred for 2 hours. The urea by-product was then removed via filtration and the cake was washed twice with DMF. To the filtrate was added 700 mL of water. The solid product emerged from solution. The slurry was cooled to 5 C. and held for at least 30 minutes. The product was collected by filtration and washed with water and then dried in vacuo at 60 C. to give 127.08 g of light tan solid.
