Yield	Reaction Conditions	Operation in experiment
41%		General procedure: Method A:16,17 A two-necked round-bottomed flask equipped with a reflux condenser and a magnetic stir bar was charged with the 2-bromobenzoic acid (20mmol) and freshly distilled methanol (25mL). The solution was heated in a hot water bath, conc. H2SO4 (8mmol) was added slowly and the reaction mixture was refluxed for 24h. After cooling to room temperature around half of the amount of the solvent was removed in vacuo and the residue was partitioned between water (50mL) and diethyl ether (70mL). The organic layer was separated and washed with saturated NaHCO3 (2×50mL), water (50mL) and brine (50mL), dried over anhydrous MgSO4 and the volatiles were removed under reduced pressure. The crude product thus obtained was purified by flash chromatography on silica gel to afford the alkyl-2-halobenzoate. (0023) In a two-necked round-bottomed flask equipped with a reflux condenser and a magnetic stir bar the alkyl 2-halobenzoate (22.5mmol) was dissolved in freshly distilled dry THF (30mL) under argon. The solution was cooled to 0C using an ice bath and NaH (60% in mineral oil, 15mmol) was added portionwise. After stirring for 15min a solution of the alkyl acetate (15mmol) in dry THF (30mL) was added dropwise to the reaction mixture at 0C. The mixture was warmed up, stirred at room temperature for 2h and heated under reflux for 24h. After cooling to room temperature around half of the amount of the solvent was removed in vacuo and the reaction mixture was diluted with toluene (50mL). The resulting mixture was washed with 2N HCl (50mL), saturated NH4Cl (50mL), dried over anhydrous MgSO4 and the volatiles were removed under reduced pressure. The crude product was purified by flash column chromatography on silica gel to afford the alkyl 3-(2?-halophenyl)-3-oxo-propanoate 1.

Dimethyl carbonate (5.2 g, 0.210 mol) was added, and then reacted at 120 C for 4 h. The mixed system was adjusted to pH = 6 with glacial acetic acid in water and extracted with CH2Cl2. The organic phase was dried over Na2SO4 and concentrated to give methyl 3-(2-chlorophenyl)-3-oxopropanoate as a light yellow oily liquid. Methyl 3-(2-chlorophenyl)-3-oxopropanoate (2.66 g, 0.175 mol) and DMF-DMA (1.88 g, 0.361 mol) were added to toluene (25 mL) and stirred at 120 C for 10 h.

K2CO3 (2.1 g, 0.361 mol) was added and the temperature was raised to 150 C to reacte for 12 h. The reaction solution was filtered, and isopropyl alcohol (5 mL) and petroleum ether (5 mL) was add to filtrate to give 1-(4-fluorophenyl)-4-oxo-1,4-dihydroquinoline-3-carboxylate as a yellow solid, which was dissolved to 1,4-dioxane (15 mL) and H2O (15 mL) and added NaOH (0.6 g, 0.146 mol).
