YieldReaction ConditionsOperation in experiment
With phosphorous pentoxide p-toluenesulfonic acid; at 130.0℃; General procedure: General Procedure A: To a pressure tube containing ethyl 4,4,4- trifluoroacetoacetate (1.2 eq) and Eaton"s reagent [7.5% wt. phosphorous pentoxide p- toluenesulfonic acid solution ( 1 mL/0.3 mmol)], was added the corresponding aniline (1 eq). Then the pressure vessel was sealed and heated to 130 , and the reaction mixture was stirred overnight. After cooling to 0 C, the reaction was poured into ice water (~5 mL/1 mmol) and the solution pH was adjusted to 5 by the addition of saturated aqueous potassium carbonate. In situations when a pale yellow precipitate was formed, the solution was filtered and the residue was washed with water and cold ethanol, then dried in vacuo to yield the crude 4-hydroxyquinoline. Alternatively, the solution could be extracted with CHCl3 (20 mL x 3) and dried over anhydrous Na2SO4. After filtration, the solvent was removed in vacuo to give the crude 4-hydroxyquinoline. Then the residue was purified by column chromatography using hexane"EtOAc as an eluent (30% of EtOAc) to give the desired products with yields ranging from 45% to 60%. (0217) Characterization data for compound 1 and 1a e have been reported by Kozikowski.

YieldReaction ConditionsOperation in experiment
In trichlorophosphate; (2) The above-mentioned compound (1.82 g) was dissolved in phosphorus oxychloride (8.00 mL), and the mixture was stirred at 70C for 2.5 hr. The reaction mixture was concentrated under reduced pressure, and saturated aqueous sodium hydrogencarbonate solution was added to the residue. The mixture was extracted with chloroform and the extract was concentrated under reduced pressure to give 4-chloro-2-trifluoromethyl-8-methylquinoline (1.66 g).

YieldReaction ConditionsOperation in experiment
In phosphoric acid; water; (1) 2-Methylaniline (5.00 g) was dissolved in 75% phosphoric acid (20 mL), and ethyl trifluoroacetoacetate (8.60 g) was dropwise added thereto at 105C. The mixture was stirred at105C for 5.5 hr. After allowing to cool, the reaction mixture was added to water. The precipitated solid was collected by filtration to give <strong>[1701-19-5]2-trifluoromethyl-4-hydroxy-8-methylquinoline</strong> (1.84 g).
