---|---|---|
92% | Phosphorus oxychloride (35 mL, 380 mmol, 8.5 eq) was cautiously added to 8-trifluoromethyl-4-quinolone (9.40 g, 44.1 mmol), followed by heating at 110C for 2hours. After cooling, the reaction mixture was gradually and cautiously poured ontoice with vigorous stirring (note: delayed exothermic reaction). After resting, theinhomogeneous mixture was made basic by the addition of 50% caustic soda, addingadditional ice to control the resulting exothermic reaction. After standing 18 hours, themixture (1000 mL) was extracted with chloroform (100 mL, followed by 3 x 50 mL). Thepooled organic layers were dried (MgSO4) and concentrated under reduced pressurewith warming to afford the desired product as a beige, crystalline solid with acharacteristic odor of 4-chloroquinoline (9.37 g, 92%). |
