YieldReaction ConditionsOperation in experiment
With thionyl chloride; N,N-dimethyl-formamide; In tetrahydrofuran; at 0 - 60℃; for 2h; Reference Example 24: Synthesis of <strong>[5467-57-2]2-chloroquinoline-4-carboxylic acid</strong> dimethylamide To a mixture of <strong>[5467-57-2]2-chloroquinoline-4-carboxylic acid</strong> (5.0 g) and THF (48 mL) was added a small amount of DMF, followed by addition of thionyl chloride (1.8 mL) with ice cooling. The mixture was stirred at room temperature for 1 h and then at 60C for 1 h. The mixture was cooled to room temperature and then concentrated under reduced pressure, and the residue was diluted with chloroform (30 mL). The mixture was ice-cooled, followed by addition of 50% aqueous dimethyl amine (20 mL), and the mixture was stirred for 10 min. 1 M aqueous sodium hydroxide was added, the mixture was extracted with chloroform, the organic layer was dried with anhydrous magnesium sulfate, then the desiccant was removed by filtration, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate = 7:3) to obtain the title compound (4.6 g). MS: ESI+ (m/z) 257 (M++Na)
With oxalyl dichloride; N,N-dimethyl-formamide; In dichloromethane; at 20℃; a) 2-Chloroquinoline-4-carbonyl chloride; <strong>[5467-57-2]2-chloroquinoline-4-carboxylic acid</strong> (0.5 g, 2.4 mmol) was slurred in 5 mL of DCM. Oxalyl chloride (0.41 mL, 4.8 mmol) was added and the reaction was started by the addition of two drops of DMF. The reaction mixture was stirred at room temperature over night. The solvent was evaporated to yield a brown solid (0.575 g) which was used without further purification.
With thionyl chloride; for 2h;Inert atmosphere; Reflux; General procedure: To cinconinic acid (1.7 g, 9.0 mmol) was added POCl3 (10 mL) under cooling and then heated to reflux for 3 h under nitrogen. The mixture was cooled to room temp, poured into ice-water and extracted with CHCl3. The combined extracts were dried over anhydrous sodium sulfate, filtered and evaporated under reduced pressure. To the residue was added thionyl chloride (10 mL), and the resulting mixture was heated to reflux under nitrogen for 2 h. The excess of thionyl chloride was then removed under reduced pressure, and ethanol (20 mL) / methanol, triethylamine (6 mL) were added at 0C. The resulting reaction mixture was heated to reflux for 30 min. The excess of alcohol was distilled off completely, and the mixture was extracted with CHCl3. The organic layer was collected, dried over anhydrous sodium sulfate and concentrated under reduced pressure to give the desired product (1.4 g, 70% yield).
