[0315]
[0316] method
[0317] In a 250 mL 3-necked round bottom flask, 3-chloro-4-fluoroaniline (20 g, 137.4 mmol) and toluene (100 mL) were added. To the reaction mixture was added diethyl-2-(ethoxymethylene)malonate (29.7 g, 137.4 mmol) at 25°C. The reaction mixture was heated at reflux and stirred for 1 h, then cooled to 30 °C and water (150 mL) was added and the mixture was extracted with EtOAc (30 mL x 3). The combined organic layers were washed with brine solution, washed with anhydrous Na 2 SO 4 Drying and concentration under reduced pressure afforded 40 g of crude product which was titrated with a minimal amount of cyclohexane to give diethyl-2-(3-chloro-4-fluorophenylamino)methylenemalonate (1) 36g, yield (50.1%); 1 H NMR (400MHz, DMSO-d 6): δ10.61(d, J=12.8,1H),8.29(d,J=13.6,1H),7.72-7.74(m,1H),7.4-7.42(m,2H),4.12-4.2(m, 4H), 1.24-1.26 (m, 6H); MS (ESI): 316.1 (M+H).

Embodiment 2
[0331] The remaining mother liquor from the synthesis of Example 1 was concentrated under reduced pressure to obtain crude 5b. The product was purified by column chromatography (silica gel) to obtain 10 mg of pure 6-(benzyl(methyl)amino)-7-chloro-1-isobutyl-4-oxo-1,4-dihydroquinoline- 3-Carboxylic acid (5b): yield, 5%; 1 H NMR (400MHz, DMSO-d 6 ):δ15.16(d,1H),8.95(s,1H),7.28-8.27(m,7H),4.41-4.43(d,2H),4.3(s,2H),2.74(s,3H), 2.1-2.2 (m, 1H), 0.88-0.90 (d, 6H); MS (ESI): 399 (M+H); HPLC: 93.57%.
Embodiment 3
[0333]
[0334] In a 25 mL single necked round bottom flask were added intermediate 4 (0.5 g, 1.679 mmol) from Example 1 and N-1-(3-(trifluoromethyl)phenyl)methanamine (1.5 g, 8.39 mmol) ) and heated to 120°C for 24h. The reaction was monitored for completion by TLC, worked up aqueous and acidified to pH 3-4 with 1 N HCl. The aqueous layer was extracted with EtOAc and the organic layer was washed with anhydrous Na 2 SO 4 dry. The solvent was evaporated under reduced pressure to obtain a crude product which was purified by silica gel column chromatography to obtain pure 6-fluoro-1-isobutyl-7-(methyl(3-(trifluoromethyl)benzyl) Amino)-4-oxo-1,4-dihydroquinoline-3-carboxylic acid (5), (25mg); Yield: 3.3%; 1 H NMR (400MHz, DMSO-d 6 ):δ15.5(s,1H),6.83-8.71(m,7H),4.75(s,2H),4.20(d,2H),3.13(s,3H),1.83-1.86(m,1H), 0.74-0.76 (d,6H); MS (ESI): 451.1 (M+H); HPLC: 92.07%.
